III PERIPHERAL BLOCK: SERIAL INTERFACE

SIO3TS0: SIO Ch.3 transmit-buffer empty/FP6 interrupt factor switching (D6) / Interrupt factor FP function switching register (0x402C5)

Switches the interrupt factor.

Write "1": SIO Ch.3 transmit-buffer empty

Write "0": FP6 input

Read: Valid

Set to "1" to use the SIO Ch.3 transmit-buffer empty interrupt.

Set to "0" to use the FP6 input interrupt.

At power-on, this bit is set to "0".

T8CH5S0: 8-bit timer 5 underflow/FP7 interrupt factor switching

(D7) / Interrupt factor FP function switching register (0x402C5)

Switches the interrupt factor.

Write "1": 8-bit timer 5 underflow

Write "0": FP7 input

Read: Valid

Set to "1" to use the 8-bit timer 5 underflow interrupt.

Set to "0" to use the FP7 input interrupt.

At power-on, this bit is set to "0".

SIO2RS1: SIO Ch.2 receive-buffer full/TM16 Ch.5 compare B interrupt factor switching

(D0) / Interrupt factor TM16 function switching register (0x402CB)

Switches the interrupt factor.

Write "1": SIO Ch.2 receive-buffer full

Write "0": TM16 Ch.5 compare B

Read: Valid

Set to "1" to use the SIO Ch.2 receive-buffer full interrupt.

Set to "0" to use the TM16 Ch.5 compare B interrupt.

At power-on, this bit is set to "0".

SIO2TS1: SIO Ch.2 transmit-buffer empty/TM16 Ch.5 compare A interrupt factor switching (D1) / Interrupt factor TM16 function switching register (0x402CB)

Switches the interrupt factor.

Write "1": SIO Ch.2 transmit-buffer empty

Write "0": TM16 Ch.5 compare A

Read: Valid

Set to "1" to use the SIO Ch.2 transmit-buffer empty interrupt.

Set to "0" to use the TM16 Ch.5 compare A interrupt.

At power-on, this bit is set to "0".

SIO3RS1: SIO Ch.3 receive-buffer full/TM16 Ch.4 compare B interrupt factor switching

(D2) / Interrupt factor TM16 function switching register (0x402CB)

Switches the interrupt factor.

Write "1": SIO Ch.3 receive-buffer full

Write "0": TM16 Ch.4 compare B

Read: Valid

Set to "1" to use the SIO Ch.3 receive-buffer full interrupt.

Set to "0" to use the TM16 Ch.4 compare B interrupt.

At power-on, this bit is set to "0".
