Indirect addressing using
Index Registers
Sends the "read information/status" explicit message command (stored in
words S+1 to S+3) to the node address specified in S, via the Communica-
tions Unit with the FINS unit address specified in bits 00 to 07 of C+1.
When the response to the explicit message is received, the response's ser-
vice data (data following the service code) is stored in the range of words
beginning at D+1.
The number of bytes of received data indicated in D is the number of bytes of
service data. (For example, if there is 1 byte of service data, D will contains
0001 hex. D will contain 0001 hex regardless of the byte order setting, i.e.,
whether the byte is stored in the rightmost or leftmost byte of D.)
The setting in bits 12 to 15 of C+1 (0 or 8 hex) determines the byte-order of
the service data stored at S+6 and D+3.
• Storing Data from the Leftmost Byte
Set bits 12 to 15 of C+1 to 0 hex.
