(d) When using the FROM command (Unusable when QCPU (Q
mode) is used)
This is used only when reading from the specified buffer memory of the
D75P2.
When using the FROM command, the transmission buffer (master module
buffer memory) for the control data and the reception buffer (master module
buffer memory) for the number of read data will be used.
The data designated with the transmission buffer is read from the D75P2
buffer memory using the intelligent device station access request signal
and complete signal (RY(n+7)E, RXS(n+7)E)).
