TXD0 (P1_4) Output serial data
RXD0 (P1_5) Input serial data
CLK0 (P1_6) Programmable I/O Port CKDIR bit in U0MR register = 0
TXD1 (P6_6) Output serial data
RXD1 (P6_7) Input serial data
CLK1 (P0_5
or P6_5)
TXD2 (P6_3) Output serial data
RXD2 (P6_4) Input serial data
CLK2 (P6_5) Programmable I/O Port CKDIR bit in U2MR register = 0
Table 15.6 lists the I/O Pin Functions in UART Mode. After the UARTi (i = 0 to 2) operating mode is selected, the
TXDi pin outputs “H” level. (If the NCH bit is set to 1 (N-channel open-drain output), this pin is in a high-
impedance state) until transfer starts.)
