II CORE BLOCK: ITC (Interrupt Controller)

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

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".

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".
