CHAPTER 14 SERIAL ARRAY UNIT
CHAPTER 14 SERIAL ARRAY UNIT
The serial array unit has four serial channels per unit and can use two or more of various serial interfaces (3-wire serial
(CSI), UART, and simplified I²C) in combination.
Function assignment of each channel supported by the 78K0R/Lx3 microcontrollers is as shown below (channels 2 and
3 of unit 1 are dedicated to UART3 (supporting LIN-bus)).

(Example of combination) When “UART0” is used for channels 0 and 1 of unit 0, CSI00 and CSI01 cannot be used,
but CSI10, UART1, or IIC10 can be used.
