These bits are only used in Host mode; do not use in Device mode.
Unimplemented: Read as ‘0’
DPPULUP: D+ Pull-Up Enable bit
1 = D+ data line pull-up resistor enabled
0 = D+ data line pull-up resistor disabled
DMPULUP: D- Pull-Up Enable bit
1 = D- data line pull-up resistor enabled
0 = D- data line pull-up resistor disabled
DPPULDWN: D+ Pull-Down Enable bit
1 = D+ data line pull-down resistor enabled
0 = D+ data line pull-down resistor disabled
DMPULDWN: D- Pull-Down Enable bit
1 = D- data line pull-down resistor enabled
0 = D- data line pull-down resistor disabled
