CompoWay/F Master Protocol
The 2nd and 3rd operands of the PMCR(260) instruction are specified as follows.
Send Data Word Allocation (2nd Operand of PMCR(260))
Receive Data Word Allocation (3rd Operand of PMCR(260))
Broadcast with ASCII Conversion, No Response
(Sequence No. 601)
This sequence converts the specified data beginning with the command code to ASCII and broadcasts it. No
responses are received.
Send Data Word Allocation (2nd Operand of PMCR(260))
First word of
send data
Note 1. Set the number of send bytes to twice the number of bytes in memory. This is necessary because the
data is converted to ASCII data before being sent.
