Description
QFP
LQFP
10
8
INT0
E
External interrupt input pin. Since this input is used as required when the
corresponding external interrupt is enabled, the port output must remain off
unless used intentionally.
P54
General-purpose I/O port. This function is enabled when external interrupt
input is disabled.
11
9
INT1
E
External interrupt input pin. Since this input is used as required when the
corresponding external interrupt is enabled, the port output must remain off
unless used intentionally.
P55
General-purpose I/O port. This function is enabled when external interrupt
input is disabled.
12
10
INT2
E
External interrupt input pin. Since this input is used as required when the
corresponding external interrupt is enabled, the port output must remain off
unless used intentionally.
P56
General-purpose I/O port. This function is enabled when external interrupt
input is disabled.
13
11
INT3
E
External interrupt input pin. Since this input is used as required when the
corresponding external interrupt is enabled, the port output must remain off
unless used intentionally.
P57
General-purpose I/O port. This function is enabled when external interrupt
input is disabled.
14
12
CKI
E
Free-running timer external clock input pin. Since this input is used as re-
quired when selected as the external clock input for the free-running timer,
the port output must remain off unless used intentionally.
INT4
External interrupt input pin. Since this input is used as required when the
corresponding external interrupt is enabled, the port output must remain off
unless used intentionally.
PG0
General-purpose I/O port. This port is enabled when free-running timer ex-
ternal clock input and external interrupt input are disabled.
15
13
PPG0
E
PPG timer 0 output pin. This function is enabled when PPG timer 0 output
is enabled.
INT5
External interrupt input pin. Since this input is used as required when the
corresponding external interrupt is enabled, the port output must remain off
unless used intentionally.
PG1
General-purpose I/O port. This port is enabled when PPG timer 0 output
and external interrupt input are disabled.
16
14
PG2
C
General-purpose I/O port.
20
18
SIN2
D
UART2 data input pin. Since this input is used as required when UART2 is
performing input operation, the port output must remain off unless used in-
tentionally.
PG3
General-purpose I/O port. This port is enabled when UART2 data input is
disabled.
