are dedicated to UART3 (supporting LIN-bus)).
7.9.1 Functional outline of serial array unit
The serial array unit has four serial channels per unit and can use two or more of various serial interfaces (three-
Function assignment of each channel supported by the 78K0R/KF3 is as shown below (channels 2 and 3 of unit 1
(Example of combination) When “UART0” is used for channels 0 and 1 of unit 0, CSI00 and CSI01 cannot be used,
Each serial interface supported by the 78K0R/KF3 has the following features.
