program
When two words are allocated, the CPU Unit uses the I/O WRITE and I/O READ
instructions, WRIT and READ, to directly access RAM. When four I/O words are
allocated, the CPU Unit uses the MOV or OUT instruction to access RAM
through the allocated I/O words.
Memory Map in the Analog Output Unit consists of 62 words. It contains conver-
sion data, status flags, and parameter setting data.
