III PERIPHERAL BLOCK: SERIAL INTERFACE

A-1

SIO3TS1: SIO Ch.3 transmit-buffer empty/TM16 Ch.4 compare A interrupt factor switching (D3) / Interrupt factor TM16 function switching register (0x402CB)

Switches the interrupt factor.

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

Write "0": TM16 Ch.4 compare A

Read: Valid

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

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

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

SIO2ES1: SIO Ch.2 receive error/TM16 Ch.3 compare B interrupt factor switching (D4) / Interrupt factor TM16 function switching register (0x402CB)

Switches the interrupt factor.

Write "1": SIO Ch.2 receive error

Write "0": TM16 Ch.3 compare B

Read: Valid

Set to "1" to use the SIO Ch.2 receive error interrupt.

Set to "0" to use the TM16 Ch.3 compare B interrupt.

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

SIO3ES1: SIO Ch.3 receive error/TM16 Ch.3 compare A interrupt factor switching (D5) / Interrupt factor TM16 function switching register (0x402CB)

Switches the interrupt factor.

Write "1": SIO Ch.3 receive error

Write "0": TM16 Ch.3 compare A

Read: Valid

Set to "1" to use the SIO Ch.3 receive error interrupt.

Set to "0" to use the TM16 Ch.3 compare A interrupt.

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

T8CH4S1: 8-bit timer 4 underflow/TM16 Ch.2 compare B interrupt factor switching (D6) / Interrupt factor TM16 function switching register (0x402CB)

Switches the interrupt factor.

Write "1": 8-bit timer 4 underflow

Write "0": TM16 Ch.2 compare B

Read: Valid

Set to "1" to use the 8-bit timer 4 underflow interrupt.

Set to "0" to use the TM16 Ch.2 compare B interrupt.

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

T8CH5S1: 8-bit timer 5 underflow/TM16 Ch.2 compare A interrupt factor switching (D7) / Interrupt factor TM16 function switching register (0x402CB)

Switches the interrupt factor.

Write "1": 8-bit timer 5 underflow

Write "0": TM16 Ch.2 compare A

Read: Valid

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

Set to "0" to use the TM16 Ch.2 compare A interrupt.

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