er operates in STOP mode, and cannot be enabled, by any

means, to operate in STOP mode.

Auto Latch Mode.

Selecting the DISABLE AUTOLATCH-

option disables the autolatches on the Port pins. These

pins will float rather than be pulled to a valid CMOS level

when they are inputs and not connected to an external sig-

nal. Selecting the ENABLE AUTOLATCHES option enables

the autolatches on the Port pins and pulls the pins to a valid

CMOS level when they are not connected to an external sig-

nal.

Port 0 Pull-Ups.

Selecting DISABLE PULL-UPS disables

the input pull-up circuitry on all Port 0 pins. Selecting EN-

ABLE PULL-UPS

enables the input pull-up circuitry on all

Port 0 pins. This option bit does not affect any of the other

port pins on the part.

Port 1 Pull-Ups.

Selecting DISABLE PULL-UPS disables

the input pull-up circuitry on all Port 1 pins. Selecting EN-

ABLE PULL-UPS

enables the input pull-up circuitry on all

Port 1 pins. This option bit does not affect any of the other

port pins on the part.

Port 2 Pull-Ups.

Selecting DISABLE PULL-UPS disables

the input pull-up circuitry on all Port 2 pins. Selecting EN-

ABLE PULL-UPS

enables the input pull-up circuitry on all

Port 2 pins. This option bit does not affect any of the other

port pins on the part.
