****************************************************
* PROGRAM - Utility subroutine to program EPROM.
* Prior to calling PROGRAM set baud rate, turn on SCI
* set X=2ms prog delay constant, and set Y=first
* address to program. SP must point to RAM.
* Bootloader leaves baud set, SCI enabled, X=4200
* and Y pointing at EPROM start ($D000) so these
* default values don’t have to be changed typically.
* Delay constant in X should be equivalent to 2 ms
*
* An external voltage source is required for EPROM
* programming.
* This routine uses 2 bytes of stack space
* Routine does not return. Reset to exit.
****************************************************
PRGROUT
* Send $FF to indicate ready for program data
WAIT1
*
DONEIT
* Loops indefinitely as long as more data sent.
at 2.1 MHz X=4200; at 1 MHz X=2000.

WAIT1
Save program delay constant
Point to internal registers
Wait for TDRE
Wait for RDRF
Get received byte
See if already programmed
If so, skip prog cycle
Put EPROM in prog mode
Write the data
Turn on prog voltage
Pull delay constant
into D-reg
But also keep delay
keep delay on stack
Delay const + present TCNT
Schedule OC1 (2ms delay)
Clear any previous flag
Turn off prog voltage
Wait for TDRE
Read from EPROM and...
Xmit for verify
Point at next location
Back to top for next
