PIN DESCRIPTION
XTAL1, XTAL2
Crystal In, Crystal Out(time-based input
and output, respectively). These pins connect a RC, paral-
lel-resonant crystal, LC, or an external single-phase clock
to the on-chip clock oscillator and buffer.
Auto Latch.
The Auto Latch puts valid CMOS levels on all
CMOS inputs (except P33, P32, P31) that are not external-
ly driven. After Power-On Reset, this level is 0 or 1 cannot
be determined. A valid CMOS level, rather than a floating
node, reduces excessive supply current flow in the input
buffer. To change the Auto Latch state, the auto latches
must be over driven with current greater than I
ALH
(high to
low) or I
ALL
(low to high).
Port 0
(P02-P00). Port 0 is a 3-bit I/O, bidirectional,
Schmitt-triggered CMOS compatible I/O port. These three
I/O lines can be configured under software control to be all
inputs or all outputs (Figure 7).
