[3] Total loop time = 6 cyc
Read status (RDRF will be set)
Read SCI data reg to clear RDRF
Wait for RDRF
Clear RDRF, don't need data
Point at start of EPROM
Delay counter (about 200ms)
Turn off RED LED
[3] Wait for Vpp to be ON

X=Tx pointer, Y=verify pointer
Send first data to target
X points at $0000 after last
Skip send if no more
Send another data char
Wait for Rx ready
Get char and clr RDRF
Does char verify ?
Skip error if OK
Done (programming failed)
Advance verify pointer
Continue till all done
