(2) 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.
The serial channel is basically the same as the one in 78K0R/KF3-L. Please refer to user manual of 78K0R/KF3-L
(U19459E) for the detail explanation of 3-wire serial (CSI) and UART interface.
