RX23W Group 38. Serial Peripheral Interface (RSPIa)
38.2.7 RSPI Sequence Status Register (SPSSR)
SPSSR indicates the sequence control status when the RSPI operates in master mode.
Any writing to SPSSR is ignored.
SPCP[2:0] Bits (RSPI Command Pointer)
The SPCP[2:0] bits indicate SPCMDm that is currently pointed to by the pointer during sequence control by the RSPI.
For the RSPI’s sequence control, refer to
section 38.3.10.1, Master Mode Operation.
SPECM[2:0] Bits (RSPI Error Command)
The SPECM[2:0] bits indicate SPCMDm that is specified by the SPCP[2:0] bits when an error is detected during
sequence control by the RSPI. The RSPI updates the SPECM[2:0] bits only when an error is detected. If both the
SPSR.OVRF and SPSR.MODF flags are 0 and there is no error, the values of the SPECM[2:0] bits have no meaning.
For the RSPI’s error detection function, refer to
section 38.3.8, Error Detection. For the RSPI’s sequence control, refer
to
section 38.3.10.1, Master Mode Operation.
