Pin function
The pin function is switched as shown below according to the combination of the operating
mode, the OS3 to OS0 bits in TCSR of the TMRX_1, and the P62DDR bit.
The pin function is switched as shown below according to the combination of the operating
mode, the OEB bit in TOCR of the FRT_1, and the P61DDR bit.
* When the ABW3 to ABW1 bits in BCRA3 to BCRA1 are all set to 1, bus width is 8 bits,
* 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.
if any are cleared to 0, bus width is 16 bits.
