Pin function
According to the setting of the PB2DDR bit, the pin function is switched as shown below.
When the ICIDE bit in TIER of the FRT_1 is set to 1, this pin functions as the FTID_1 input
pin. When the SIMOD1 and SIMOD0 bits (IHI signal) in TCONRI of the timer connection_1
are set to 01, this pin functions as the CSYNCI_1 input pin.
According to the combination of the HOE bit in TCONRO of the timer connection_0, the OS3
to OS0 bits in TCSR of the TMR1_0, and the PB1DDR bit, the pin function is switched as
shown below.
According to the combination of the VOE bit in TCONRO of the timer connection_0, the OEA
bit in TOCR of the FRT_0, and the PB0DDR bit, the pin function is switched as shown below.
