The methods of computing the maximum time required from execution of the
SEND(090), RECV(098), and CMND(490) instructions until processing is
completed are described in this section.
The transmission delay for the SEND(090) instruction can be calculated using
the following equation, which is illustrated in the following diagram.
CPU Bus Unit Service Cycle (Local Node)
The processing time will be as follows, depending on the CPU processing
mode settings at the CPU Unit:
