38.4.4 RSPI Idle Event Output
(1) In Master Mode
In master mode, an event is output when the condition for setting the IDLNF flag (RSPI idle flag) to 0 is satisfied.
(2) In Slave Mode
In slave mode, an event is output when the SPCR.SPE bit is set to 0 (RSPI is initialized).
38.4.5 Transmission-Completed Event Output
During both SPI operation and clock synchronous operation in master mode, an event is output under the condition for
setting the IDLNF flag (RSPI idle flag) from 1 to 0.
Whether the operation is in master mode or slave mode, an event is not output if 0 is written to the SPCR.SPE bit in
transmission or the SPCR.SPE bit is cleared by the mode fault error.
