• Manufacturer Part Number: h8s-2649
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2600 Series
• Manufacturer: Renesas Electronics Corporation.

• P35/SCK1/SCK4/IRQ5
The pin function is switched as shown below according to the combination of the C/A bit in SMR
of SCI_1 or SCI_4, the CKE0 and CKE1 bits in SCR, and the P35DDR bit. Do not set
simultaneously SCK1 and SCK4 to output.
Note:
• P34/RxD1
The pin function is switched as shown below according to the combination of the RE bit in SCR
of SCI_1 and P34DDR bit.
Note:
• P33/TxD1
The pin function is switched as shown below according to the combination of the TE bit in SCR of
SCI_1 and P33DDR bit.
