- Always set the UA0MOD0 register while communication is stopped, and do not rewrite it during communication.
- When specifying LSCLK×2 for the clock, enable the operation of the 2×low-speed clock by setting bit 2 (ENMLT)
- When selecting the P42 pin as the receive data input pin, it is necessary to configure settings for the Port 4 secondary

UA0MOD0
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 receive data input pin for the UART0.
