I/O
Port 3:
Port 3 is an I/O port with a user-configurable output types. During reset Port 3
latches are configured in the input only mode with the internal pull-up disabled. The
operation of port 3 pins as inputs and outputs depends upon the port configuration
selected. Each port pin is configured independently. Refer to
Section 8.12.1 “Port
configurations”
and
Table 13 “DC electrical characteristics”
for details.
All pins have Schmitt triggered inputs.
Port 3 also provides various special functions as described below:
P3.0 —
Port 3 bit 0.
XTAL2 —
Output from the oscillator amplifier (when a crystal oscillator option is
selected via the FLASH configuration).
CLKOUT —
CPU clock divided by 2 when enabled via SFR bit (ENCLK - TRIM.6). It
can be used if the CPU clock is the internal RC oscillator, Watchdog oscillator or
external clock input, except when XTAL1/XTAL2 are used to generate clock source
for the real time clock/system timer.
P3.1 —
Port 3 bit 1.
XTAL1 —
Input to the oscillator circuit and internal clock generator circuits (when
selected via the FLASH configuration). It can be a port pin if internal RC oscillator or
Watchdog oscillator is used as the CPU clock source,
and
if XTAL1/XTAL2 are not
used to generate the clock for the real time clock/system timer.
Ground:
0 V reference.
Power Supply:
This is the power supply voltage for normal operation as well as Idle
and Power-down modes.
