29.4.8 Interrupts
The SIOF has one type of interrupt.
(1) Interrupt
Sources
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.

Name Function Name
Description
1 TDREQ
Transmit
FIFO
transfer
request
The transmit FIFO stores data of
specified size or more.
2
Transmission
TFEMP
Transmit FIFO empty
The transmit FIFO is empty.
3
RDREQ
Receive FIFO transfer
request
The receive FIFO stores data of
specified size or more.
4
Reception
RFFUL
Receive FIFO full
The receive FIFO is full.
5
TCRDY
Transmit control data
ready
The transmit control register is ready
to be written.
6
Control
RCRDY
Receive control data
ready
The receive control data register
stores valid data.
7 TFUDF
Transmit
FIFO
underflow
Serial data transmit timing has arrived
while the transmit FIFO is empty.
8
TFOVF
Transmit FIFO overflow Write to the transmit FIFO is
performed while the transmit FIFO is
full.
9
RFOVF
Receive FIFO overflow Serial data is received while the
receive FIFO is full.
10 RFUDF
Receive
FIFO
underflow
The receive FIFO is read while the
receive FIFO is empty.
11
FSERR
FS error
A synchronous signal is input before
the specified bit number has been
passed (in slave mode).
12
Error
SAERR
Assign error
The same slot is specified in both
serial data and control data.
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.
