III PERIPHERAL BLOCK: SERIAL INTERFACE

A-1

SIO2RS0: SIO Ch.2 receive-buffer full/FP1 interrupt factor switching (D1) / Interrupt factor FP function switching register (0x402C5)

Switches the interrupt factor.

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

Write "0": FP1 input

Read: Valid

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

Set to "0" to use the FP1 input interrupt.

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

SIO3ES0: SIO Ch.3 receive error/FP2 interrupt factor switching

(D2) / Interrupt factor FP function switching register (0x402C5)

Switches the interrupt factor.

Write "1":	SIO Ch.3 receive error
Write "0":	FP2 input
Read: Valid
Set to "1" to use the SIO Ch.3 receive error interrupt.
Set to "0" to use the FP2 input interrupt.
At power-on, this bit is set to "0".
SIO2TS0: SIO Ch.2 transmit-buffer empty/FP3 interrupt factor switching
(D3) / Interrupt factor FP function switching register (0x402C5)
Switches the interrupt factor.
Write "1": SIO Ch.2 transmit-buffer empty
Write "0":	FP3 input	B-III
Read: Valid

Set to "1" to use the SIO Ch.2 transmit-buffer empty interrupt. Set to "0" to use the FP3 input interrupt.

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

SIO3RS0: SIO Ch.3 receive-buffer full/FP4 interrupt factor switching (D4) / Interrupt factor FP function switching register (0x402C5)

Switches the interrupt factor.

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

Write "0": FP4 input

Read: Valid

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

Set to "0" to use the FP4 input interrupt.

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

T8CH4S0: 8-bit timer 4 underflow/FP5 interrupt factor switching

(D5) / Interrupt factor FP function switching register (0x402C5)

Switches the interrupt factor.

Write "1": 8-bit timer 4 underflow

Write "0": FP5 input

Read: Valid

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

Set to "0" to use the FP5 input interrupt.

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