If the device has Vcc and PVcc, provide Vcc (pin 18) and PVcc (pin 20) to the VIN pin of the P1
connector. If the condition is Vcc = PVcc and the device that does not have both Vcc and PVcc is
used, provide Vcc (pin 18) or PVcc (pin 20) to the two VIN pins of the P1 connector.
When the target microcomputer requires port control during on-board programming, connect
necessary port signals. For details, refer to table 3.5 in section 3.2.8, S3, S4, S5, and S6 Setting
