1. Press RETURN on your keyboard If the board and the PC are still communicating correctly you will see the EVMBug prompt and the register display Move switch S4 from RESET to OUT to bring the MCU in the programming socket out of reset in bootstrap mode Now any of the commands BULK CHCK COPY ERASE PROG or VERF can be entered using the syntax shown in chapter 3 of the Evaluation Module User s Manual Remove power to the programming socket by moving switch S4 to RESET and switch S5 to OFF Remove the programmed MCU from the programming socket MOTOROLA Engineering Bulletin Examples Three programming examples are included here Example 1 This example shows how to reprogram the CONFIG register This is useful for disabling the internal EEPROM and EPROM so that the user can replace the resident MC68HC11 and program EEPROM on other chips e Type PROG 103F 103F 0C You should see MC68HC11 NOT BLANK ENTER RETURN TO CONTINUE e Press Return Then you should see 103F MC68HC11 DOES NOT VERIFY e To verify that programming did take place move switch S4 from OUT to RESET then back to OUT e Now type COPY 103F 103F E000 e Then type MD E000 The Does not verify message appears because new values in the CONFIG register do not take effect until a reset occurs However copying the value back to user memory and displaying it allows you to verify programming success Now you can exchange your programmed MCU with the MCU in the r2. the message MC68HC11 DOES NOT VERIFY then programming was unsuccessful and you will need to erase the part MOTOROLA Engineering Bulletin Motorola reserves the right to make changes without further notice to any products herein Motorola makes no warranty representation or guarantee regarding the suitability of its products for any particular purpose nor does Motorola assume any liability arising out of the application or use of any product or circuit and specifically disclaims any and all liability including without limitation consequential or incidental damages Typical parameters which may be provided in Motorola data sheets and or specifications can and do vary in different applications and actual performance may vary over time All operating parameters including Typicals must be validated for each customer application by customer s technical experts Motorola does not convey any license under its patent rights nor the rights of others Motorola products are not designed intended or authorized for use as components in systems intended for surgical implant into the body or other applications intended to support or sustain life or for any other application in which the failure of the Motorola product could create a situation where personal injury or death may occur Should Buyer purchase or use Motorola products for any such unintended or unauthorized application Buyer shall indemnify and hold Motorola and its officers employees sub

6. listed here Do not make these modifications if you intend to program the MC68HC811A8 General Infomation Hardware Preparation The EVM is shipped with an MC68HC11A1 in the resident MCU socket U2 You may use this chip to program any MC68HC11 A or E series devices Many users will object at this point saying What about jumper J20 Jumper J20 merely determines what on board memory resources are available in the expanded multiplexed emulation mode If J20 is on pins 1 and 2 then the RAM device addressed from C000 to DFFF is not visible thereby allowing proper emulation of an A series device which only contains an 8 K ROM addressed from E000 to FFFF If J20 is on pins 2 and 3 then the RAM chip from C000 to DFFF is enabled allowing the user to emulate properly the MC68HC11E9 which contains 12 K of ROM from D000 to FFFF Jumper J20 must be on pins 2 and 3 for E series programming and is ignored for A series programming Be aware of the internal memory map of the device you are trying to program the EVM must have some memory resource available that uses the addresses you are trying to program Toward that end install jumpers J10 and J11 to enable the on board memory resources from E000 FFFF and B600 B7FF respectively Ensure that an 8 K RAM is installed in U15 to enable memory from COO00 DFFF Some problems with programming MC68HC11 devices on the EVM are due to a noisy clock line to the programming socket Th
