11.1 Functions of Serial Array Unit
11.1.1 3-wire serial I/O (CSI00, CSI10)
The serial array unit has four serial channels per unit and can use two or more of various serial interfaces (3-wire
Function assignment of each channel supported by the 78K0R/KE3 is as shown below (channels 2 and 3 of unit 1
(Example of combination) When “UART1” is used for channels 2 and 3 of unit 0, CSI10 and IIC10 cannot be used,
Each serial interface supported by the 78K0R/KE3 has the following features.
This is a clocked communication function that uses three lines: serial clock (SCK) and serial data (SI and SO) lines.
[Data transmission/reception]
[Clock control]
[Interrupt function]
[Error detection flag]
