• 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.
P45DDR 0 1
HI12E 0 0 1
Pin Function P45 input pin P45 output pin HIRQ12 output pin
TMRI1 input pin, CSYNCI input pin
*
Note: * When bits CCLR1 and CCLR0 in TCR1 of TMR_1 are set to 1, this pin is used as the
TMRI1 input pin. It can also be used as the CSYNCI input pin.
• 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.
HOE 0 1
OS3 to OS0 All 0 Not all 0 —
P44DDR 0 1 — —
HI12E — 0 1 — —

• 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.
P43DDR 0 1
HI12E — 0 1
P43 input pin P43 output pin HIRQ11 output pinPin Function
TMCI1 input pin, HSYNCI input pin
*
Note: * When the external clock is selected by bits CKS2 to CKS0 in TCR1 of TMR_1, this pin
is used as the TMCI1 input pin. It can also be used as the HSYNCI input pin.
