I/O Write (IOW)
Use the I/O Write instruction to send information to I/O modules. This instruction is
particularly useful for writing data to:
D nonĆReliance I/O modules that are only byteĆaccessible
D any modules that have not been configured
Use the I/O Write instruction to write a:
D byte Ċ This is used for modules that support only 8Ćbit addressing
D double byte Ċ This should only be used for nonĆReliance modules that contain
16Ćbit data but only support 8Ćbit Multibus accesses
D integer (16Ćbits)
D double integer (32Ćbits)
When EN becomes true, the Processor writes the amount of I/O data you specified in
the location you specified.
