PORT1 consists of the two 8-bit bidirectional I/O ports P1L and
P1H. It is bit-wise programmable for input or output via
direction bits. For a pin configured as input, the output driver is
put into high-impedance state.
The following Port 1 pins also serve for alternate functions:
P1L.0
CC60
CAPCOM6: Input / Output of Ch. 0
P1L.1
COUT60
CAPCOM6: Output of Channel 0
P1L.2
CC61
CAPCOM6: Input / Output of Ch. 1
P1L.3
COUT61
CAPCOM6: Output of Channel 1
P1L.4
CC62
CAPCOM6: Input / Output of Ch. 2
P1L.5
COUT62
CAPCOM6: Output of Channel 2
P1L.6
COUT63
Output of 10-bit Compare Channel
P1L.7
CTRAP
CAPCOM6: Trap Input
CTRAP is an input pin with an internal pullup resistor. A low
level on this pin switches the compare outputs of the
CAPCOM6 unit to the logic level defined by software.

XTAL1:
Input to the oscillator amplifier and input to the
internal clock generator
Output of the oscillator amplifier circuit.
To clock the device from an external source, drive XTAL1,
while leaving XTAL2 unconnected. Minimum and maximum
high/low and rise/fall times specified in the AC Characteristics
must be observed.
XTAL2:
RSTIN
69
I
Reset Input with Schmitt-Trigger characteristics. A low level at
this pin for a specified duration while the oscillator is running
resets the C164CI. An internal pullup resistor permits power-
on reset using only a capacitor connected to
V
SS
.
In bidirectional reset mode (enabled by setting bit BDRSTEN
in register SYSCON) the RSTIN line is pulled low for the
duration of the internal reset sequence upon a software or
WDT reset.
