Pin function
PA0/A16/KIN8/SSE0I
The function of port A pins is switched as shown below according to the combination of the
SSE bit in SEMR of SCI_0, the C/A bit in SMR, the CKE1 bit in SCR, the CS256E and IOSE
bits in SYSCR, the ADFULLE bit in BCR2 of BSC, and the PA0DDR bit.
Address 13 in the following table is expressed by the following logical expression:
When the KMIM8 bit in KMIMRA of the interrupt controller is cleared to 0, this pin can be
used as the KIN8 input pin. To use this pin as the KIN8 input pin, clear the PA0DDR bit to 0.
PA1/KIN9/SSE2I
The function of port A pins is switched as shown below according to the combination of the
SSE bit in SEMR of SCI_2, the C/A bit in SMR, the CKE1 bit in SCR, and the PA1DDR bit.
When the KMIM9 bit in KMIMRA of the interrupt controller is cleared to 0, this pin can be
used as the KIN9 input pin. To use this pin as the KIN9 input pin, clear the PA1DDR bit to 0.
