Rev. 1.1
A start bit followed by nine low bits is a break signal. (See
When the monitor receives a break signal, it drives the PTB0 pin high for
the duration of two bits before echoing the break signal.
The monitor ROM uses the following commands:
•
•
•
•
•
•
READ (read memory)
WRITE (write memory)
IREAD (indexed read)
IWRITE (indexed write)
READSP (read stack pointer)
RUN (run user program)
