PB7DDR
Pin function
PB6DDR
Pin function
According to the setting of the PB7DDR 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_0, this pin
functions as the TMCI1_0 input pin. When the CCLR1 and CCLR0 bits in TCR of the
TMR1_0 are all set to 1, this pin functions as the TMRI1_0 input pin. When the SIMOD1 bit
(IHI signal) in TCONRI of the timer connection_0 is set to 1, this pin functions as the
HSYNCI_0 input pin.
According to the setting of the PB6DDR bit, the pin function is switched as shown below.
When the ICIAE bit in TIER of the FRT_0 is set to 1, this pin functions as the FTIA_0 input
pin. When the SIMOD1 and SIMOD0 bits (IVI signal) in TCONRI of the timer connection_0
are all set to 1, this pin functions as the VSYNCI_0 input pin.
