Description
Input to the on-chip inverting oscillator amplifier
To use the internal oscillator, a crystal/resonator circuit is connected to this
pin. If an external oscillator is used, its output is connected to this pin.
Output of the on-chip inverting oscillator amplifier
To use the internal oscillator, a crystal/resonator circuit is connected to this
pin. If an external oscillator is used, leave XTAL2 unconnected.
PLL Low Pass Filter input
Receive the RC network of the PLL low pass filter.
Description
Port 0
P0 is an 8-bit open-drain bidirectional I/O port. Port 0
pins that have 1s written to them float and can be used
as high impedance inputs. To avoid any parasitic current
consumption, Floating P0 inputs must be pulled to V
V
Port 1
P1 is an 8-bit bidirectional I/O port with internal pull-ups.
Port 2
P2 is an 8-bit bidirectional I/O port with internal pull-ups.
Port 3
P3 is an 8-bit bidirectional I/O port with internal pull-ups.
Port 4
P4 is an 2-bit open drain port.
