Temporary routing receive
Direct receive
When the clock exceeds 20 MHz, it should not be set to 1. Also, FARB Bit renewal must be carried out
during software reset.
In temporary buffer receive mode, the packet data containing any errors is left at page 00 if the receive
terminates abnormally (CRC error, etc.). The copy to "SID page" corresponding to the received source ID
(Receive SID) is not executed (the received data is discarded).
In direct receive mode, the packet data containing errors is left at “SID page” even if the receive terminates
abnormally (CRC error, etc.).
Regardless of whether the receive is done through temporary buffer or direct receive, the RXF# flag upon
abnormal termination of receive is set to 0 (not completed). It does not matter which receive process is
being used because free format mode assumes that the receive is always checked with the RXF# flag. *
On the contrary, the receive process is important in the remote buffer receive mode with direct receive. *
In the worst case, if SID is corrupted in the received packet, the packet data may be written to the wrong
page.
