Calibration
Circuitry

Functional. Both analog input and
analog output can be fully calibrated.
The CALDACs default to 0 V.

Nonfunctional. Draws negligible power.
5 V supply is ideally zero, but gets
negligible voltage. The CALDACs
default to 0 V. Calibration constants
(digital values) written into the
CALDAC are not preserved and must be
rewritten after entering normal mode.

Digital I/O

Functional. Defaults to high impedance
inputs for all ports. Protected from
–0.5 to 5.5 V.

Functional. Defaults to high impedance
inputs for all ports (A, B, and C).
Protected from –0.5 to 5.5 V.

Counters

Functional. Initialize to undefined states.
Individual counters of the 82C53 must
be fully programmed before use.
Protected from –0.5 to 5.5 V.

Functional. Initialize to undefined states.
