****************************************************
* BOOTLOADER FIRMWARE FOR 68HC711E9 - 21 Aug 89
****************************************************
* Features of this bootloader are...
*
* Auto baud select between 7812.5 and 1200 (8 MHz)
* 0 - 512 byte variable length download
* Jump to EEPROM at $B600 if 1st download byte = $00
* PROGRAM - Utility subroutine to program EPROM
* UPLOAD - Utility subroutine to dump memory to host
* Mask I.D. at $BFD4 = $71E9
****************************************************
* Revision A -
*
* Fixed bug in PROGRAM routine where the first byte
* programmed into the EPROM was not transmitted for
* verify.
* Also added to PROGRAM routine a skip of bytes
* which were already programmed to the value desired.
*
* This new version allows variable length download
* by quitting reception of characters when an idle
* of at least four character times occurs
*
****************************************************
* EQUATES FOR USE WITH INDEX OFFSET = $1000
