P60 functins as an input pin only (no output)
For serial signal transmission application, the Pin P60 is used as a serial signal
input pin. For detailed usage and function, refer to Section 8.8,

of this Spec.
7 GIOP pins.
The pull high resistors (200K Ohms) and pull low resistors (15K Ohm) are
selected through pin programming.
All Port6 I/O pins are used for AD function. Furthermore,P64 & P65 can also be
used for PWM function.
Port7 offers up to 8 GIOP pins. The sink current of P70 & P71 are
programmable for driving LED.
Each pin has pull high resistors (200K Ohm) that can be selected through pin
programming.
All Port7 I/O pins can be used for AD function.
USB Plus data line interface or PS/2 line interface are user-defined through
firmware setting.
When this pin is used as a PS/2 line interface, it will generate an interrupt when
its state changes.
USB Minus data line interface or PS/2 line interface are user-defined through
firmware setting.
When this pin is used as a PS/2 line interface, it will generate an interrupt when
its state changes.
Connects to the USB power source or to a nominal 5V-power supply. Actual V
