27.2
Table 27.1 shows the SCIF pin configuration. Since the pin functions are the same in each
channel, the channel number is omitted in the description below.
Table 27.1 Pin Configuration
Note: These pins are made to function as serial pins by performing SCIF operation settings with
Pin Name
SCIFn_SCK (n = 0, 1)
SCIFn_RXD (n = 0, 1)
SCIFn_TXD (n = 0, 1)
SCIFn_CTS (n = 0, 1)
SCIFn_RTS (n = 0, 1)
the C/A bit in SCSMR, the TE, RE, CKE1, and CKE0 bits in SCSCR, and the MCE bit in
SCFCR. Break state transmission and detection can be set in SCSPTR of the SCIF.
