is executed once more in the next cycle. Execution of this second instruction is
repeated until all the data in the receive buffer has been processed. For this rea-
son, it takes at least two cycles for transfer of all the data to be completed and the
instruction to start to be output.
Note Depending on the timing of IOWR instructions, transfer errors may not be
reflected in the CPU Unit. (For details, refer to 5-1 Transferring and Saving
Data.)
A sample program is provided below for writing the indicated speed data to the
PCU. The beginning word address of the transfer data is to be D00500, and the
other settings are as indicated. The data will be transferred to the PCU desig-
nated as unit number 2.
