I/O
Port 3:
Port 3 is an 2-bit I/O port with a user-configurable output type. 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
8.11.1 “Port configurations”
and
Table 7 “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.
