Pin Function
P45/TMRI1/HIRQ12/CSYNCI
The pin function is switched as shown below according to the combination of the HI12E bit in
SYSCR2 and the P45DDR bit.
P44/TMO1/HIRQ1/HSYNCO
The pin function is switched as shown below according to the combination of the HI12E bit in
SYSCR2, the OS3 to OS0 bits in TCSR of TMR_1, the HOE bit in TCONRO of the timer
connection function, and the P44DDR bit.
P43/TMCI1/HIRQ11/HSYNCI
The pin function is switched as shown below according to the combination of the HI12E bit in
SYSCR2 and the P43DDR bit.
* When bits CCLR1 and CCLR0 in TCR1 of TMR_1 are set to 1, this pin is used as the
