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
polarized to 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 8-bit bidirectional I/O port with internal pull-ups.
Port 5
P5 is a 4-bit bidirectional I/O port with internal pull-ups.
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. X1 is the clock source for internal timing.
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 X2 unconnected.
PLL Low Pass Filter input
FILT receives the RC network of the PLL low pass filter.
