13.2.4 UART0 Mode Register 0 (UA0MOD0)
Address: 0F292H
Access: R/W
Access size: 8/16 bit
Initial value: 00H
UA0MOD0 is a special function register (SFR) to set the transfer mode of the UART.

•Always set the UA0MOD0 register while communication is stopped, and do not rewrite it during communication.
•When specifying LSCLK X 2 for the clock, enable the operation of the low-speed double clock by setting bit 2
(ENMLT) of the frequency control register 1 (FCON1) to “1”.
•When selecting the P42 pin as the received data input pin, it is necessary to configure settings for the Port 4
secondary functions. For the secondary functions of Port 4, see Chapter 17, “Port 4”.
R/W
U0IO (bit 0)
U0CK1, U0CK0 (bits 2, 1)
U0RSEL (bit 4)
The U0IO bit is used to select transmit or receive mode.
The U0CK1 and U0CK0 bits are used to select the clock to be input to the baud rate generator of the UART0.
The U0RSEL bit is used to select the received data input pin for the UART0.
U0RSS (bit 5)
U0RSS is the bit that selects the UART0 received data input sampling timing.
