MON166 User's Guide
The MON166 Monitor has the following requirements:
MCU compatible with 80C166, C161, C163, C164, C165, C167, or
- Software trap for breakpoints (NMI is typical).
Ten (10) words of stack space in the user program being
- 256 bytes of off-chip data memory (RAM).
5K bytes of off-chip code memory (ROM) loaded with the MON166
monitor. RAM may be used with the MCU in bootstrap mode.
Serial interface. This may be the on-chip UART, a simulated
UART (using two port pins), or an external UART (like the 16450 or
16550 used on standard PC's).
MON166 requires only the TRANSMIT DATA and RECEIVE
DATA RS-232/V.24 signals along with GROUND. In some
cases, additional connections are necessary to enable
communications (for example, loop-back connections for DTR, DSR,
RTS, CTS, and DCD).
Following are the required pins for standard connectors.
