Remark
CFnDIR
[In single transfer mode]
[In continuous transfer mode]
The reception completion interrupt (INTCFnR) occurs when communication is
complete.
Even if transmission is enabled (CFnTXE bit = 1), the transmission enable interrupt
If the next transmit data is written during communication (CFnSTR.CFnTSF bit =
1), it is ignored and the next communication is not started. Also, if reception-only
communication is set (CFnTXE bit = 0, CFnRXE bit = 1), the next communication
is not started even if the receive data is read during communication (CFnSTR.
CFnTSF bit = 1).
The continuous transmission is enabled by writing the next transmit data during
communication (CFnSTR.CFnTSF bit = 1).
Writing the next transmission data is enabled after a transmission enable interrupt
(INTCFnT) occurs.
If reception-only communication is set (CFnTXE bit = 0, CFnRXE bit = 1) in the
continuous transfer mode, the next reception is started immediately after a
reception completion interrupt (INTCFnR), regardless of the read operation of the
CFnRX register.
Therefore, immediately read the receive data from the CFnRX register. If this read
operation is delayed, an overrun error (CFnOVE bit = 1) occurs.
(INTCFnT) does not occur.
