The CN7 connector allows connecting the PG-LPC flash programming software to the DemoKit-KA1
board to program application programs in the CPU’s internal flash memory. Connection CN7 provides
the board power supply of 5V, and also UART6 of the 78K0S/KA1+ device to the host system.
Connector CN1 is used to define the operating clock of the DemoKit-KA1 board. Closing the connectors
CN1/3–5 and CN1/4–6 (default setting) provides an 8 MHz clock frequency to the MCU. In this mode,
the clock frequency is supplied by the CPLD.
Alternatively, an external crystal oscillator can be equipped to the DemoKit-KA1 board. To use this
mode, close connectors CN1/1–3 and CN1/2–4.
Connectors CN2 and CN12 allow you to connect and disconnect external board hardware to the MCU.
A 10K potentiometer R24 is connected between V
V
connector CN12/5–6.
The reference voltage of the potentiometer R24 can be supplied to the AV
CN12/3–4.
