13.3.1.5 Commands
Data Sheet
166
NOTE:
The monitor ROM firmware uses these commands:
The monitor ROM firmware echoes each received byte back to the PTA0 pin for
error checking. An 11-bit delay at the end of each command allows the host to send
a break character to cancel the command. A delay of two bit times occurs before
each echo and before READ, IREAD, or READSP data is returned. The data
returned by a read command appears after the echo of the last byte of the
command.
Wait one bit time after each echo before sending the next byte.
A brief description of each monitor mode command is given in
