• First address (word m+5)
When CIO (0001), WR (0002), DM (0003), or EM area (0004) is specified
for the operation data area in the area type specification (word m+4 bit08
to 14), the first address is to be specified.
Set the first address in hexadecimal (Hex). The setting range varies de-
pending on the setting of the No. of transferred words (word m+4 bit00 to
07).
When setting the No. of transferred words to its maximum "A0 Hex (160)",
the setting ranges are as follows:
CIO area: 0000 to 175F Hex (0 to 5983)
WR area: 0000 to 015F Hex (0 to 351)
DM area: 0000 to 7F5F Hex (0 to 32607)
EM area: 0000 to 7F5F Hex (0 to 32607)
When "Does not use the general I/O area (00)" is specified in the area type
specification (word m+4 bit 08 to 14), this setting is not necessary.
