Section 29 Serial I/O with FIFO (SIOF)
29.4.8
The SIOF has one type of interrupt.
(1)
Interrupts can be issued by several sources. Each source is shown as an SIOF status in SISTR.
Table 29.14 lists the SIOF interrupt sources.
Table 29.14 SIOF Interrupt Sources
Whether an interrupt is issued or not as the result of an interrupt source is determined by the SIIER
settings. If an interrupt source is set to 1 and the corresponding bit in SIIER is set to 1, an SIOF
interrupt is issued.

Description
The transmit FIFO stores data of
specified size or more.
The transmit FIFO is empty.
The receive FIFO stores data of
specified size or more.
The receive FIFO is full.
The transmit control register is ready
to be written.
The receive control data register
stores valid data.
Serial data transmit timing has arrived
while the transmit FIFO is empty.
performed while the transmit FIFO is
full.
receive FIFO is full.
The receive FIFO is read while the
receive FIFO is empty.
the specified bit number has been
passed (in slave mode).
The same slot is specified in both
serial data and control data.
