7.8. Analog I/O (J1 and J14)

Three of the C8051T62x/32x target device's port pins are connected to the J1 terminal block. The terminal block also allows users to input an external voltage that can be used as the power supply of the board. Refer to Table 3 for the J1 terminal block connections. Placing a shorting block on J14 will connect the P0.7/VREF signal on J1 to the P0.7 pin of the device.

7.9. VPP Connection (J15)

The C8051T62x/32x devices require an external 6.0 V programming voltage applied to the VPP pin during device programming. The VPP pin on these devices is shared with P1.5 or P1.1 depending on the device. During programming, the VPP voltage is automatically enabled when needed. Header J15 is provided to allow the user to disconnect the programming circuitry from the VPP pin to avoid interfering with the normal application operation of the GPIO pin. When programming the device, J15 should be shorted with a shorting block. When running normal application code, J15 can be removed. See Table 4 for more information on which port pins are shared with VPP.
