PORT1 consists of one 8-bit and one 6-bit bidirectional I/O
port P1L and P1H. Each pin can be programmed for input
(output driver in high-impedance state) or output.
The following PORT1 pins also serve for alt. functions:
CC22IO: [CAPCOM2] CC22 Capture Inp./Compare Outp.
EX0IN: [Fast External Interrupt 0] Input (default pin),
CC23IO: [CAPCOM2] CC23 Capture Inp./Compare Outp.
EX1IN: [Fast External Interrupt 1] Input (default pin),
MRST1: [SSC1] Master-Receive/Slave-Transmit In/Out.
EX2IN: [Fast External Interrupt 2] Input (default pin),
MTSR1: [SSC1] Master-Transmit/Slave-Receive Out/Inp.
T7IN: [CAPCOM2] Timer T7 Count Input,
SCLK1: [SSC1] Master Clock Output / Slave Clock Input,
EX3IN: [Fast External Interrupt 3] Input (default pin),
CC24IO: [CAPCOM2] CC24 Capture Inp./Compare Outp.,
EX4IN: [Fast External Interrupt 4] Input (default pin)
CC25IO: [CAPCOM2] CC25 Capture Inp./Compare Outp.,
EX5IN: [Fast External Interrupt 5] Input (default pin)
Note: At the end of an external reset P1H.4 and P1H.5 also
may input startup configuration values
XTAL2 61
O
XTAL2: Output of the oscillator amplifier circuit
XTAL1 60
I
XTAL1: Input to the oscillator amplifier and input to the
internal clock generator
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.

Note: Input pin XTAL1 belongs to the core voltage domain.
Therefore, input voltages must be within the range
defined for V_DDI.
Reference voltage for the A/D converter
Reference ground for the A/D converter
Digital Core Supply Voltage (On-Chip Modules):
+2.5 V during normal operation and idle mode.
