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)
