PROGRAM
UPLOAD
****************************************************
* UPLOAD - Utility subroutine to send data from
* inside the MCU to the host via the SCI interface.
* Prior to calling UPLOAD set baud rate, turn on SCI
* and set Y=first address to upload.
* Bootloader leaves baud set, SCI enabled, and
* Y pointing at EPROM start ($D000) so these default
* values do not have to be changed typically.
* Consecutive locations are sent via SCI in an
* infinite loop. Reset stops the upload process.
