• PG2/ExIRQ10/ExTMIX
The pin function is switched as shown below according to the PG2DDR bit. When the TMIXS
bit in PTCNT0 and the CCLR1 and CCLR0 bits in TCR of TMR_X are cleared to 0, this pin is
used as the ExTMIX (ExTMRIX) input pin. When the ISS10 bit in ISSR16 is set to 1 and the
IRQ10E bit in IER16 of the interrupt controller is set to 1, this pin can be used as the ExIRQ10
input pin.
PG2DDR
Pin function
• PG1/ExIRQ9/ExTMCI1
The pin function is switched as shown below according to the PG1DDR bit. When the
TMCI1S bit in PTCNT0 is set to 1 and the external clock is selected by the CKS2 to CKS0
bits in TCR of TMR_1, this bit is used as the ExTMCI1 input pin. When the ISS9 bit in
ISSR16 is set to 1 and the IRQ9E bit in IER16 of the interrupt controller is set to 1, this pin
can be used as the ExIRQ9 input pin.
PG1DDR
Pin function
• PG0/ExIRQ8/ExTMCI0
The pin function is switched as shown below according to the PG0DDR bit. When the
TMCI0S bit in PTCNT0 is set to 1 and the external clock is selected by the CKS2 to CKS0
bits in TCR of TMR_0, this bit is used as the ExTMCI0 input pin. When the ISS8 bit in
ISSR16 is set to 1 and the IRQ8E bit in IER16 of the interrupt controller is set to 1, this pin
can be used as the ExIRQ8 input pin.
