Section 22 Serial I/O with FIFO (SIOF)
Regarding Interrupt Source: The transmit sources and receive sources are signals indicating the
SIOF state; after being set, if the state changes, they are automatically cleared by the SIOF.
When the DMA transfer is used, a DMA transfer request of the FIFO is disabled for one cycle at
the end of that DMA transfer.
Processing when Errors Occur: On occurrence of each of the errors indicated as a status in
SISTR, the SIOF performs the following operations.
• Transmit FIFO underflow (TFUDF)
• Transmit FIFO overflow (TFOVF)
• Receive FIFO overflow (RFOVF)
• Receive FIFO underflow (RFUDF)
• FS error (FSERR)
• Assign error (SAERR)

The immediately preceding transmit data is again transmitted.
The contents of the transmit FIFO are protected, and the write operation causing the overflow
is ignored.
Data causing the overflow is discarded and lost.
An undefined value is output on the bus.
The internal counter is reset according to the signal in which an error occurs.
If the same slot is assigned to both serial data and control data, the slot is assigned to serial
If the same slot is assigned to two control data items, data cannot be transferred correctly.
