I/O Description
General-Purpose I/O Ports A–D
PA[7:0]
I/O Port A. These pins are used for general purpose I/O.
PB[7:0]
I/O Port B. These pins are used for general purpose I/O. PB6 and PB7 are
available only in those devices without an ADC.
PC[7:0]
I/O Port C. These pins are used for general purpose I/O.
PD[0]
I/O Port D. This pin is used for general purpose output only.
Note: PB6 and PB7 are only available in 28-pin packages without ADC. In 28-pin packages with ADC, they are re-
placed by AV_DD and AV_SS.
Timers
T0OUT/T1OUT
O Timer output 0–1. These signals are the output from the timers.
T0OUT/T1OUT
O Timer complement output 0–1. These signals are output from the timers in
PWM DUAL OUTPUT Mode.
T0IN/T1IN
I Timer Input 0–1. These signals are used as the capture, gating and counter
inputs. The T0IN signal is multiplexed T0OUT signals.
Comparator
CINP/CINN
COUT
I Comparator inputs. These signals are the positive and negative inputs to
the comparator.
O Comparator output. This is the output of the comparator.
Analog
ANA[7:0]
V_REF
I Analog port. These signals are used as inputs to the analog-to-digital con-
verter (ADC).
I/O Analog-to-digital converter reference voltage input.
Note: When configuring ADC using external V_REF, PB5 is used as V_REF in
28-pin package.
Note: The AV_DD and AV_SS signals are available only in the 28-pin packages with ADC. They are replaced by PB6
and PB7 on 28-pin packages without ADC.
