RL78/G1A CHAPTER 12 SERIAL ARRAY UNIT
R01UH0305EJ0200 Rev.2.00 504
Jul 04, 2013
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 and CSI01. 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 CSI10, UART1, and IIC10.
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 four types of communication operations.
• UART transmission (See 12.6.1.)
• UART reception (See 12.6.2.)
• LIN transmission (UART2 only) (See 12.7.1.)
• LIN reception (UART2 only) (See 12.7.2.)
