11.5.8 Procedure for processing errors that occurred during 3-wire serial I/O (CSI00, CSI10) communication
described in Figure 11-70.
Remark
418
Reads serial data SDR0n register.
Reads SSR0n register.
Writes SIR0n register
The procedure for processing errors that occurred during 3-wire serial I/O (CSI00, CSI10) communication is
Software Manipulation
n: Channel number (n = 0, 2)
Figure 11-70. Processing Procedure in Case of Overrun Error
The BFF = 0, and channel n is enabled
to receive data.
Error flag is cleared.
CHAPTER 11 SERIAL ARRAY UNIT
User’s Manual U17854EJ9V0UD
Hardware Status
This is to prevent an overrun error if the
next reception is completed during error
processing.
Error type is identified and the read
value is used to clear error flag.
Only error generated at the point of
reading can be cleared, by writing the
value read from the SSR0n register to
the SIR0n register without modification.
