Components and Basic Functions

OPU

’s basic components and their functions are as follows.

1. R5F212K4SDFP in MCU uses 8Mhz external clock to communicate with the system

card via UART. Communication standard is 9600bps UART.

2. OP consists of 21 keys. Buttons 1~20 are connected to the MCU GPIO PORT via

Matrix so that they detect which button is pressed. The power button is connected

to the Power Management IC in the system card.
