Pin function
According to the setting of the PB5DDR bit, the pin function is switched as shown below.
When the ICIDE bit in TIER of the FRT_0 is set to 1, this pin functions as the FTID_0 input
pin. When the SIMOD1 and SIMOD0 bits (IHI signal) in TCONRI of the timer connection_0
are set to 01, this pin functions as the CSYNCI_0 input pin.
According to the setting of the PB4DDR bit, the pin function is switched as shown below.
When the external clock is selected by the CKS2 to CKS0 bits in TCR of the TMR1_1, this pin
functions as the TMCI1_1 input pin. When the CCLR1 and CCLR0 bits in TCR of the
TMR1_1 are all set to 1, this pin functions as the TMRI1_1 input pin. When the SIMOD1 bit
(IHI signal) in TCONRI of the timer connection_1 is set to 1, this pin functions as the
HSYNCI_1 input pin.
According to the setting of the PB3DDR bit, the pin function is switched as shown below.
When the ICIAE bit in TIER of the FRT_1 is set to 1, this pin functions as the FTIA_1 input
pin. When the SIMOD1 and SIMOD0 bits (IVI signal) in TCONRI of the timer connection_1
are all set to 1, this pin functions as the VSYNCI_1 input pin.
