Field

Description

7:0

PTBPE[7:0]

Internal Pullup Enable for Port B Bits — Each of these control bits determines if the internal pullup device is

enabled for the associated PTB pin. For port B pins that are configured as outputs, these bits have no effect and

the internal pullup devices are disabled.

0 Internal pullup device disabled for port B bit n.

1 Internal pullup device enabled for port B bit n.
