Pin Name
Serial clock pin
Receive data pin
Transmit data pin
Note: They are made to function as serial pins by performing SCI operation settings with the TE,
RE, CKEI, and CKE0 bits in SCSCR1 and the C/
and detection can be performed by means of a setting in the SCI's SCSPTR1 register.
Table 18.3 shows the SCIF I/O port pin configuration.

Modem control pin
Note: These pins function as the MD0, MD1, MD2, MD7, and MD8 mode input pins after a power-
on reset. These pins are made to function as serial pins by performing SCIF operation
settings with the TE, RE, CKE1, and CKE0 bits in SCSCR2 and the MCE bit in SCFCR2.
Break state transmission and detection can be set in the SCIF's SCSPTR2 register.
