D.1
Board description
The CP320-Post is an optionally available tool which is used for hardware and software debug-
ging. During the startup process of the CP321 it provides the user with information about the
status of the boot process by means of a message code similar to the POST codes on the Intel
PC. When the board has completed the startup process, the CP320-Post may be used to pro-
vide debug information for software development. The programmer can, therefore, define his
own debug code and send it to the CP320-Post by making a byte write command to the first
address of the socket memory area. The address for accessing the Post module depends on
the DIL socket (1 or 2) in which it is inserted and the setting of jumper J1 on the CP321.

SHORT CIRCUIT DANGER
When installing and operating the CP320-Post module ensure that

other portions of the CP321 except the connections to the DIL
socket.
