I
5-V supply pins.
3,34
I
Ground pins.
24
I
Master clock input from external clock source.
SERIAL PORT AND TIMER SIGNALS
RXD
48
I
Asynchronous mode receive input.
TXD
47
O/Z
Asynchronous mode transmit output.
TCLK1
10
I
Timer 1 clock. If external clock is selected, it serves as clock input to Timer 1.
TCLK2
11
I
Timer 2 clock. If external clock is selected, it serves as clock input to Timer 2.
WDT
23
O

I/O
16 bit I/O lines that can be individually configured as inputs or outputs and also individually set or
reset
when configured as outputs.
COMPARE AND CAPTURE SIGNALS

O
Compare outputs. The states of these pins are determined by the combination of compare and action
registers.
CAP0
CAP1

I
Capture inputs. A transition on these pins causes the timer register to be captured in FIFO stack.
CMP4/CAP2
66
I/O
This pin can be configured as compare output or capture input.
CMP5/CAP3
65
I/O
This pin can be configured as compare output or capture input.
Input/Output/High-impedance state.
