Pin function
P44/IRQ4/TMIX/ExMCCMDDIR/ExMCCSB
The pin function is switched as shown below according to the combination of the MCIF
operating mode and the P44DDR bit.
When the TMIXS bit in PTCNT0 is cleared to 0 and the external clock is selected by the CKS2
to CKS0 bits in TCR of TMR_X, this pin is used as the TMCIX input pin. When the CCLR1
and CCLR0 bits in TCR of TMR_X are set to 1, this pin is used as the TMRIX input pin.
When the ISS4 bit in ISSR is cleared to 0 and the IRQ4E bit in IER of the interrupt controller
is set to 1, this pin can be used as the IRQ4 input pin. To use this pin as the IRQ4 input pin,
clear the P44DDR bit to 0.
P43/IRQ3/TMO1/ExMCDATDIR/ExMCCSA/HSYNCO
The pin function is switched as shown below according to the combination of the MCIF
operating mode, the HOE bit in TCONRO of the timer connection, the OS3 to OS0 bits in
TCSR of TMR_1, and the P43DDR bit. When the ISS3 bit in ISSR is cleared to 0 and the
IRQ3E bit in IER of the interrupt controller is set to 1, this pin can be used as the IRQ3 input
pin. To use this pin as the IRQ3 input pin, clear the P43DDR bit to 0.
