function
When the TIOCC0/TCLKAS bit in PTCNT2 is set to 1, this pin can be used as the
ExTIOCC0/ExTCLKA pin.
According to the TPU channel 0 settings by the OS3 to OS0 bits in TCSR of the TMR0_0, the
MD3 to MD0 bits in TMDR_0, the IOC3 to IOC0 bits in TIORL_0, and the CCLR2 to CCLR0
bits in TCR_0, and the combination of the TPSC2 to TPSC0 bits in TCR_0 to TCR_2, the
TIOCC0/TCLKAS bit, and the PA2DDR bit, the pin function is switched as shown below.
2. When TIOCC0/TCLKAS = 1 and TPSC2 to TPSC0 in one of TCR_0 to TCR_2 = B'100,
3. Output is disabled for TIOCD0. When BFA = 1 or BFB = 1 in TMDR0, output is disabled
pin functions as the TIOCC0 input pin.
this pin functions as the TCLKA input pin. When TIOCC0/TCLKAS = 1 and phase-count
mode is set to the TCR channel 1, this pin functions as the TCLKA input pin.
and the setting is the same as (2).
