64. s to start at address 0x0000 and the user EPROM can contain only one ROM disk 5 4 BURNING A ROM DISK INTO PROM The I option causes an image file to be produced The optional number following the I option specifies the actual start address of the start of the ROM disk The start address is required for ROMable EXE files The default address is 0x000 The R specifies the RXE interrupt number The default number is 90 Hex The S option causes ROM disk to include sub directories found in the source sub directory selected to include on the ROM disk image The T option is the test option This option causes the ROMDISK utility to display statistics on the ROM disk but not to actually create the image file or hex This is useful when you need to make sure that the required files fit in the available space The V str option allows you to set the volume label to something other than ROMDISK The volume label string can be up to 11 characters and must be in quotes The Z option allows you to specify the sector size of the ROM disk The default sector size is 128 bytes Legal values for this option are 128 256 and 512 NOTE Cis not supported Use an EXE file compression utility if a compressed disk is required To support this the system would not be able to boot from floppy or hard disk and would use 6K more ROM and 12K more RAM Once all options and devices have been set to your liking it is time to burn it
65. the CM102 You can program up to 16 rows by 8 col umns in an X Y matrix The keypad matrix can be any combinations of rows and columns up to 16 rows by 8 columns such as the simple 4 x 4 matrix shown in Figure 4 1 Whenever a key is pressed a connection is made between the column and the row to which the keyswitch is connected Column 1 Column 2 Column 3 Column 4 Row 1 Row 2 Row 3 Row 4 Data Buffer Fig 4 1 Simple 4 x 4 Keypad Switch Matrix To ensure accurate translation of keystrokes the CMF8680 BIOS scans all keys on a regular basis and transfers the scan code data to the system The BIOS performs switch debouncing and ghost key detection The BIOS also implements 2 key rollover where two is the maximum number of keys that can be pressed simultaneously on the keypad before it is not possible to correctly detect other keys being pressed Figure 4 2 shows the scanning algorithm used by the CMF8680 with the CM102 s scanning feature enabled 6 4 Get scan address Read switch array using scan address Compare with buffer Next scan address All rows done Yes Debounce key Translate to scan code Generate interrupt Transfer scan code to system Get repeat scan code Fig 4 2 Scanning Algorithm The scan codes are programmed into the 2K bit area of the EEPROM available to the user Programming is done from the system configuration program RTDMOD EXE To use
66. the baud rate to on startup The available baud rates are 300 1200 2400 4800 9600 19200 38400 57600 and 115200 COM Setthe communications port to COM1 and COM2 are sup ported 8N1 Set the serial port to 8 data bits no parity 1 stop bit 7E1 Set the serial port to 7 data bits even parity 1 stop bit No other parameters for data bits besides 8N1 and 7E1 are currently supported 3 24 Environment Variable Commands Terminal Emulation An environment variable COMM is supported which may set certain communications parameters The switches are identical to the command line options Example SET COMM COM2 B2400 7E1 This sets COMM to start up using COM2 at 2400 baud with 7 data bits even parity and 1 stop bit If new options are specified on the command line they override the environment variable settings Invalid options are ignored Most commands are entered by pressing an Alt letter combination Some commands take effect immediately such as changing the baud rate while others require further information such as a file name before continuing Esc is the general abort key If you do not wish to execute a command or want to stop a command while it is going such as a file transfer simply press the Esc key and you will be back in terminal mode Alt B Set the baud rate This command toggles between all the avail able baud rates Continue to press Alt B until the baud rate you wish ap
