Serial Peripheral Interface (S08SPI16V1)
the flag bits to determine what event caused the interrupt. The service routine should also clear the flag
bit(s) before returning from the ISR (usually near the beginning of the ISR).
15.4.10.1 MODF
MODF occurs when the master detects an error on the SS pin. The master SPI must be configured for the
MODF feature (see
changed:
The MODF interrupt is reflected in the status register MODF flag. Clearing the flag will also clear the
interrupt. This interrupt will stay active while the MODF flag is set. MODF has an automatic clearing
process which is described in
15.4.10.2 SPRF
SPRF occurs when new data has been received and copied to the SPI receive data buffer. In 8-bit mode,
SPRF is set only after all 8 bits have been shifted out of the shift register and into SPIxDL. In 16-bit mode,
SPRF is set only after all 16 bits have been shifted out of the shift register and into SPIxDH:SPIxDL.
Once SPRF is set, it does not clear until it is serviced. SPRF has an automatic clearing process which is
described in
before the end of the next transfer (i.e. SPRF remains active throughout another transfer), the latter
transfers will be ignored and no new data will be copied into the SPIxDH:SPIxDL.
15.4.10.3 SPTEF
SPTEF occurs when the SPI transmit buffer is ready to accept new data. In 8-bit mode, SPTEF is set only
after all 8 bits have been moved from SPIxDL into the shifter. In 16-bit mode, SPTEF is set only after all
16 bits have been moved from SPIxDH:SPIxDL into the shifter.
Once SPTEF is set, it does not clear until it is serviced. SPTEF has an automatic clearing process which is
described in
15.4.10.4 SPMF
SPMF occurs when the data in the receive data buffer is equal to the data in the SPI match register. In 8-bit
mode, SPMF is set only after bits 8–0 in the receive data buffer are determined to be equivalent to the value
in SPIxML. In 16-bit mode, SPMF is set after bits 15–0 in the receive data buffer are determined to be
equivalent to the value in SPIxMH:SPIxML.
