Description
I/O lines with pull-high resistors (bit option). I/O modes of each line are controlled
by related control register bit (PAC).
Each line of PA can be optioned as a wake-up input (bit option).
I/O configurations: Schmitt trigger/CMOS.
The PA3, PA4 and PA5 are pin-shared with PFD, TMR and INT, respectively.
I/O lines with pull-high resistors (bit option).
I/O modes of each line are controlled by related control register bit (PBC).
I/O configurations: Schmitt trigger/CMOS.
Each PB line is pin shared with an A/D converter input.
I/O lines with pull-high resistors (bit option).
I/O modes of each line are controlled by related control register bit (PDC).
I/O configurations: Schmitt trigger/CMOS.
A resistor connected across OSC1 and VSS or a crystal across OSC1 and OSC2
will generate the system clock.
Schmitt trigger reset input. Active low.
Positive power supply
Negative power supply, ground.
