18.3.1.5 Echoing
As shown in
pin for error checking.
Any result of a command appears after the echo of the last byte of the command.
18.3.1.6 Break Signal
A start bit followed by nine low bits is a break signal. See
signal, it drives the PTA0 pin high for the duration of two bits before echoing the break signal.
18.3.1.7 Commands
The monitor ROM uses these commands (see
