RL78/G1D
Select any function for each channel. Only the selected function is possible. If UART0 is selected for channels 0 and 1
of unit 0, for example, these channels cannot be used for CSI00. At this time, however, channel 2, 3, or other channels of
the same unit can be used for a function other than UART0, such as UART1.
Caution When using a serial array unit for UART, both the transmitter side (even-numbered channel) and the
receiver side (odd-numbered channel) can only be used for UART.
UART performs the following two types of communication operations.
● UART transmission
● UART reception
