Table 24.7 lists the I/O Pin Functions in UART Mode.
After UART2 operating mode is selected, the TXD2 pin outputs a high-level signal until transfer starts. (When N-
channel open-drain output is selected, this pin is in the high-impedance state.)
Figure 24.7 shows the Transmit Timing in UART Mode. Figure 24.8 shows the Receive Timing in UART Mode.

• When TXD2 (P11_1)
• When TXD2 (P11_2)
• For reception only:
• When RXD2 (P11_1)
• When RXD2 (P11_2)
• For transmission only:
CLK2SEL0 bit in U2SR1 register = 0
CLK2SEL0 bit in U2SR1 register = 1
CKDIR bit in U2MR register = 1
PD11_0 bit in PD11 register = 0
CTS2SEL0 bit in U2SR1 register = 1
CRD bit in U2C0 register = 0
CRS bit in U2C0 register = 0
PD11_3 bit in PD11 register = 0
CTS2SEL0 bit in U2SR1 register = 1
CRD bit in U2C0 register = 0
CRS bit in U2C0 register = 1
CTS2SEL0 bit in U2SR1 register = 0
Bits TXD2SEL1 to TXD2SEL0 in U2SR0 register = 10b (P11_1)
When N-channel open-drain output is selected,
PD11_1 bit in PD11 register = 0
Bits TXD2SEL1 to TXD2SEL0 in U2SR0 register = 01b (P11_2)
When N-channel open-drain output is selected,
PD11_2 bit in PD11 register = 0
P11_1 and P11_2 can be used as ports by setting TXD2SEL1 to
TXD2SEL0 to 00b.
Bits RXD2SEL1 to RXD2SEL0 in U2SR0 register = 01b (P11_1)
Bits RXD2SEL1 to RXD2SEL0 in U2SR0 register = 10b (P11_2)
PD11_2 bit in PD11 register = 0
P11_1 and P11_2 can be used as ports by setting RXD2SEL1 to
RXD2SEL0 to 00b.
