Interrupt
input or
Segment 37
output
Selectable as external interrupt schmitt trigger
input or LCD segment 37 signal output by mask
option. External interrupt schmitt trigger input
with pull-high resistor. Edge triggered activated
on a high to low transition. INT shares pad with
SEG37.

Segment
Output
Selectable as 32768Hz crystal oscillator or LCD
segment signal output by mask option. Crystal
oscillator (32.768kHz) for Timer 3 and LCD
clock.
XIN shares pad with SEG39; XOUT
shares pad with SEG38.
