TXD0 (P13_1) Serial data output
RXD0 (P13_2
or P11_4)
CLK0 (P13_3) Programmable I/O port CLK0SEL0 bit in U0SR register = 0 (CLK0 pin not used)

RXD1 (P4_1)
CLK1 (P4_2)
Table 23.7 lists the I/O Pin Functions in UART Mode.
After the UARTi (i = 0 or 1) operating mode is selected, the TXDi pin outputs a high-level signal until transfer
starts. (When the NCH bit is set to 1 (N-channel open-drain output), this pin is in the high-impedance state.)

TXD0SEL0 bit in U0SR register = 1
When N-channel open-drain output is selected,
PD13_1 bit in PD13 register = 0
For reception only:
P13_1 can be used as a port by setting TXD0SEL0 bit = 0.
• RXD0 (P13_2)
• RXD0 (P11_4)
• For transmission only:
CLK0SEL0 bit in U0SR register = 1
CKDIR bit in U0MR register = 1
PD13_3 bit in PD13 register = 0
TXD1SEL0 bit in U1SR register = 1
When N-channel open-drain output is selected,
PD4_0 bit in PD4 register = 0
For reception only:
P4_0 can be used as a port by setting TXD1SEL0 bit = 0.
RXD1SEL0 bit in U1SR register = 1
PD4_1 bit in PD4 register = 0
For transmission only:
P4_1 can be used as a port by setting RXD1SEL0 bit = 0.
CLK1SEL0 bit in U1SR register = 1
CKDIR bit in U1MR register = 0
PD4_2 bit in PD4 register = 0
Bits RXD0SEL1 to RXD0SEL0 in U0SR register = 01b (P13_2)
PD0_2 bit in PD0 register = 0
Bits RXD1SEL1 to RXD0SEL0 in U0SR register = 10b (P11_4)
PD6_4 bit in PD6 register = 0
P13_2 and P11_4 can be used as a port by setting bits
RXD0SEL1 to RXD0SEL0 = 00b.
