3.4.6 Addressing
3.4.6.1 I/O Module Data
The CPU has direct access to the bus terminal data through absolute
addresses. Addressing is organized word-by-word and begins with the address
0 both with inputs and outputs. The corresponding addresses for bits, bytes
and double words (dword) are derived from the word addresses.
