4. GPIOs are connected to other hardware and you do not want the E86MON software disturbing that hardware This variable is useful only for Am186CC CH CU and Am186ED microcontroller devices The refresh_hz variable defines the rate at which the refresh cycles occur The default rate is 64 KHz which provides 512 refresh cycles every 8 ms Note that the actual refresh rate is not correct unless the cpuspeed permanent variable matches the actual CPU clock speed Version 3 4 2 of the E86MON software has replaced the waitstates permanent variable in prior versions of E86MON software with the umcs_ws and Imcs_ws variables These variables enable you to configure the upper and lower memory chip select wait states Version 3 4 2 of the E86MON software initially sets UMCS to three wait states and sets LMCS to zero wait states then loads the number of wait states for both registers from the umcs_ws and Imcs_ws Note that these variables are only used when the E86MON software is running on a system with an Am186CC CH CU or Am186ED microcontroller Locations between this variable and the monitor upgrade sector Figure 1 2 on page 1 5 of the user s manual are not erased by the XA command You can still erase a specific sector with the X lt sector number gt command E86MON Software User s Manual Amendment AMENDMENT AMD Emergency Recovery for Am186CC CH CU and Am186ED Microcontroller Boards If you program the DRAM refresh and or memory chip sele

M and then back destroying any user program already loaded The E86MON software supports the following permanent variables autorun baudrate cpuspeed hhkey led refresh_hz waitstates protectflash When this variable is non zero it selects which EXE program to load from the Flash memory and to run at boot time The W command is used to store EXE programs into Flash memory The EXE programs can be listed using the L command This variable defines the default baud rate used if an a is not detected during the three second autobaud period at boot Note that the baud rate is not correct unless the cpuspeed variable is also correct This variable defines the speed from the CPU to the monitor The cpuspeed variable is required for correct default baud rate setup and correct DRAM refresh rate selection Am186CC CH CU and Am186ED devices only The cpuspeed variable is also used to set the internal timer tick correctly The internal timer tick is used by benchmark programs and also governs the speed of the LED patterns This variable should be only non zero when the monitor is running on a Hamilton Hallmark formerly now Avnet Personal Computer Components keychain system The hhkey vari able sets up various GPIOs correctly for this system When this variable is non zero the monitor uses the LEDs to show current status When the led variable is zero the monitor does not change the LEDs Set the variable to zero if the LED
7. ct permanent variables to values that are not bootable on the Am186CC CH CU and Am186ED microcontroller boards the E86MON software does not start up However you can tie address pin 8 on the data bus High with a weak pullup so pin 8 is sampled by the reset configuration register on the Am186CC CH CU or Am186ED microcontroller This starts up the upper memory chip select at three wait states and sets the DRAM refresh rate to 15 6 us at 5 MHz This enables the E86MON software to come up which enables you to reprogram the permanent variables with appropriate values so the E86MON software can start up on its own R Display Alter Register The R command can be used with the following registers BX CS CX DI DS DX EX IP SI SP and SS UTILITIES INCLUDED WITH THE E86MON SOFTWARE This section updates Appendix B of the user s manual The MAKEHEX Utility Different versions of the E86MON software use different versions of MAKEHEX Ensure that your version of software matches the version of MAKEHEX being used You will receive an error message if the incorrect version of MAKEHEX is used The MAKEHEX utility with version 3 4 x of the monitor has changed from previous versions The HEX files built with the older version 3 2 x MAKEHEX utility do not download with the version 3 4 x monitor The version 3 4 x MAKEHEX files do not execute on a version 3 2 x monitor ERROR MESSAGES This section updates Appendix C of the user s manual The

9. ote Two builds of the E86MON software are available One build is for the Am186 ER Am188 ER microcontrollers and one is for the other Am186 and Am188 microcontroller devices The traditional version of E86MON software is too large to be contained in the 32K of SRAM on the SD186ER microcontroller demonstration board so a separate build was created that does not include support for the other microcontrollers The Am186ER Am188ER microcontroller HEX file version of the E86MON software uses E_ER as the first four characters of its filename The other version uses EMON as the first four characters of its filename Publication 21891 Rev B Amendment 1 Issue Date October 1999 AMD AMENDMENT The files listed below are in the OUT subdirectory on the floppy disk for all boards except the SD186ER microcontroller board EMON342U HEX Main upgrade file EMON342R HEX RAM based version of the E86MON software EMON342B HEX Bootable suitable for programming with a PROM programmer version of the E8S6MON software EXTEM342 HEX Extensions to provide support for a DOS emulator Int21 command line editor additional LED patterns and help Note The 342 portion of the filename represents version 3 4 2 The version included on your floppy disk may vary The files listed below are in the OUT subdirectory on the floppy disk for the SD186ER microcontroller board _ER342U HEX Main upgrade file _ER342B H
