Pin Functions
The relationship between register setting values and pin functions are as follows. Note that MMC
mode stands for MultiMediaCard mode, and the symbol “—” stands for Don't care in the tables.
•
P47/
IRQ7
/TMOY
The pin function is switched as shown below according to the combination of the OS3 to OS0
bits in TCSR of TMR_Y and the P47DDR bit.
When the ISS7 bit in ISSR is cleared to 0 and the IRQ7E bit in IER of the interrupt controller
is set to 1, this pin can be used as the
IRQ7
input pin. To use this pin as the
IRQ7
input pin,
clear the P47DDR bit to 0.
OS3 to OS0
All bits are set as 0
One bit is set as 1

/TMOX
The pin function is switched as shown below according to the combination of the OS3 to OS0
bits in TCSR of TMR_X and the P46DDR bit.
When the ISS6 bit in ISSR is cleared to 0 and the IRQ6E bit in IER of the interrupt controller
is set to 1, this pin can be used as the
IRQ6
input pin. To use this pin as the
IRQ6
input pin,
clear the P46DDR bit to 0.

P45/
IRQ5
/TMIY
The pin function is switched as shown below according to the P45DDR bit.
When the TMIYS bit in PTCNT0 is cleared to 0 and the external clock is selected by the CKS2
to CKS0 bits in TCR of TMR_Y, this pin is used as the TMCIY input pin. When the CCLR1
and CCLR0 bits in TCR of TMR_Y are set to 1, this pin is used as the TMRIY input pin.
When the ISS5 bit in ISSR is cleared to 0 and the IRQ5E bit in IER of the interrupt controller
is set to 1, this pin can be used as the
IRQ5
input pin. To use this pin as the
IRQ5
input pin,
clear the P45DDR bit to 0.
