P65 input pin
• P64/FTCI_1/D4
The pin function is switched as shown below according to the combination of the operating
mode and the P64DDR bit.
When the CKS1 and CKS0 bits in TCR of the FRT_1 are all set to 1, this pin functions as an
FTCI_1 input pin.

Note:
* When the ABW3 to ABW1 bits in BCRA3 to BCRA1 are all set to 1, bus width is 8 bits,
if any are cleared to 0, bus width is 16 bits.
