Preliminary
Independently regulated Bi-directional I/O port — V
High-voltage Bi-directional I/O port.
Sourced from V
use, to reduce current consumption.
Master clear (reset) input/programming voltage input. This
pin is an active low reset to the device. Voltage on the MCLR/
V
of programming mode.
Oscillator crystal output. Connects to crystal or resonator in
crystal oscillator mode. In RC mode, OSC2/CLKOUT output
is connected to TMR0, bit 0. Frequencies of CLKIN/8 to
CLKIN/1024 can be generated on this pin.
Positive supply.
Ground reference.
Clock input to Timer 0. Must be tied to V
Oscillator crystal input/external clock source input.
PP
pin must not exceed V
