I/O lines with pull-high resistors (bit option). I/O modes of each line are con-
trolled by related control register bit (PAC). Each line of PA can be optioned
as a wake-up input (bit option). I/O configurations: Schmitt trigger/CMOS
I/O lines with pull-high resistors (bit option). I/O modes of each line are con-
trolled by related control register bit (PBC). I/O configurations: Schmitt trig-
ger/CMOS. Each PB line is pin shared with an A/D converter input.
I/O lines with pull-high resistors (bit option). I/O modes of each line are con-
trolled by related control register bit (PCC). I/O configurations: Schmitt trig-
ger/CMOS.
I/O lines with pull-high resistors (bit option). I/O modes of each line are con-
trolled by related control register bit (PDC). I/O configurations: Schmitt trig-
ger/CMOS. The PD0~PD3 can be selected as PWM outputs. INT0/INT1
are falling/rising edge selectable triggers.
A resistor across OSC1 and VDD or a crystal across OSC1 and OSC2 will
generate a system clock.
32768Hz crystal across OSC3 and OSC4 will generate RTC clock signal
which only provides system timing.

LCD highest voltage; should be connected to VDD with external resistor.
LCD segment signal driving outputs SEG7~SEG10 can be optioned as out-
