Description
LCD Common Driver0
LCD Common Driver1
LCD Common Driver2
LCD Common Driver3
chip select control for parallel slave port (See related RD and WR)
USART Synchronous Data. Always associated RX pin function. (See
related RX, TX, CK)
GP is a bi-directional I/O port. Some pins of port GP can be software
programmed for internal weak pull-ups on the inputs.
TTL input buffer as general purpose I/O, Schmitt Trigger input buffer
when used as the serial programming mode.
TTL input buffer as general purpose I/O, Schmitt Trigger input buffer
when used as the serial programming mode.
External Interrupt
Master clear (reset) input or programming voltage input. This pin is
an active low reset to the device.
These pins should be left unconnected.
Oscillator crystal input or external clock source input. ST buffer when
configured in RC mode. CMOS otherwise.
Oscillator crystal output. Connects to crystal or resonator in crystal
oscillator mode. In RC mode, OSC2 pin outputs CLKOUT which has
1/4 the frequency of OSC1, and denotes the instruction cycle rate.
Input with weak pull-up resistor, can be used to generate an interrupt.
Parallel Slave Port for interfacing to a microprocessor port. These
pins have TTL input buffers when PSP module is enabled.
PORTA is a bi-directional I/O port.
RA4 is an open drain when configured as output.
CMOS = CMOS compatible input or output
PU = Weak internal pull-up
AN = Analog input or output
O = output
L = LCD Driver
