2:
Voltage spikes at the MCLR pin may cause latch-up. A series resistor of greater than 1 k
Ω
should be used
to pull MCLR to V
DD
, rather than tying the pin directly to V
DD
.
3:
PORTD and PORTE are not implemented on the PIC16CR73/76 devices.
NOTICE: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation of the device at those or any other conditions above those
indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability.
