Overview
Section 7-1
For general I/O area A in the MC Unit, allocations are specified by setting the
[PORT_A transfer area type at MC Unit] (m+74) and the [PORT_A transfer
first address at MC Unit] (m+75) of [General I/O area range setting] in the allo-
cated DM area.
Note
m: DM Area for CPU Bus Unit words D30000 to D31599 (100 words per Unit
according to Unit No.)
Relationship between MC Unit Transfer Area Type, Transfer First
Address, and Number of Transfer Words
The following combinations cannot be transferred. If these combinations are
specified, the data will not be transferred, but an error will not occur.
