Selection Method and Pin Functions
P44/TMO1/
HIRQ1/HSYNCO
The pin function is switched as shown below according to the combination of
bit HI12E in SYSCR2, bits OS3 to OS0 in TCSR of TMR1, bit HOE in
TCONRO of the timer connection function, and bit P44DDR.

TMCI1 input pin, HSYNCI input pin
When an external clock is selected with bits CKS2 to CKS0 in TCR1 of TMR1,
this pin is used as the TMCI1 input pin. It can also be used as the HSYNCI
input pin.
P42/TMRI0/
SCK2/SDA1
The pin function is switched as shown below according to the combination of
bit ICE in ICCR of IIC1, bits CKE1 and CKE0 in SCR of SCI2, bit C/
A in SMR
of SCI2, and bit P42DDR.

I/O pin
TMRI0 input pin
When this pin is used as the SDA1 I/O pin, bits CKE1 and CKE0 in SCR of
SCI2 and bit C/
A in SMR of SCI2 must all be cleared to 0. SDA1 is an NMOS-
only output, and has direct bus drive capability.
When bits CCLR1 and CCLR0 in TCR0 of TMR0 are set to 1, this pin is used
as the TMRI0 input pin.
