Field Description
7
PTHPE7
Pull Enable for Port H Bit 7
This control bit determines if the internal pullup device is enabled for the associated PTH pin. For port H
pins that are configured as outputs or Hi-Z, these bits have no effect.
0 Pullup disabled for port H bit 7.
1 Pullup enabled for port H bit 7.
6
PTHPE6
Pull Enable for Port H Bit 6
This control bit determines if the internal pullup device is enabled for the associated PTH pin. For port H
pins that are configured as outputs or Hi-Z, these bits have no effect.
0 Pullup disabled for port H bit 6.
1 Pullup enabled for port H bit 6.
5–3
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
