I
P1.5 — Port 1 bit 5 (input only).
I
RST — External Reset input during power-on or maybe a
reset input/output if selected via UCFG1 and UCFG2. When
functioning as a reset input or input/output, a LOW on this
pin resets the microcontroller, causing I/O ports and
peripherals to take on their default states, and the processor
begins execution at address 0. When functioning as a reset
output or input/output an internal reset source will drive this
pin LOW. Also used during a power-on sequence to force
ISP mode. When using an oscillator frequency above
12 MHz, the reset input function of P1.5 must be
enabled. An external circuit is required to hold the
device in reset at power-up until VDD has reached its
specied level. When system power is removed VDD will
fall below the minimum specied operating voltage.
When using an oscillator frequency above 12 MHz, in
some applications, an external brownout detect circuit
may be required to hold the device in reset when VDD
falls below the minimum specied operating voltage.

AD04 — ADC0 channel 4 analog input.
P2.0 to P2.5
I/O
Port 2: Port 2 is an 8-bit I/O port with a user-congurable
output type. During reset Port 2 latches are congured in the
input only mode with the internal pull-up disabled. The
operation of Port 2 pins as inputs and outputs depends upon
the port conguration selected. Each port pin is congured
independently. Refer to Section 7.13.1 “Port congurations”
and Table 11 “Static characteristics” for details.
All pins have Schmitt triggered inputs.
Port 2 also provides various special functions as described
below:
P2.0/AD07
