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⁾
1 = D+ data line pull-down resistor enabled
0 = D+ data line pull-down resistor disabled
DMPULDWN: D- Pull-Down Enable bit⁽¹⁾
1 = D- data line pull-down resistor enabled
0 = D- data line pull-down resistor disabled
VBUSON: VBUS Power-on bit⁽¹⁾
1 = VBUS line powered
0 = VBUS line not powered
OTGEN: OTG Features Enable bit⁽¹⁾
1 = USB OTG enabled; all D+/D- pull-ups and pull-downs bits are enabled
0 = USB OTG disabled; D+/D- pull-ups and pull-downs are controlled in hardware by the settings of the
HOSTEN and USBEN bits (U1CON<3,0>)
VBUSCHG: VBUS Charge Select bit⁽¹⁾
1 = VBUS line set to charge to 3.3V
0 = VBUS line set to charge to 5V
VBUSDIS: VBUS Discharge Enable bit⁽¹⁾
1 = VBUS line discharged through a resistor
0 = VBUS line not discharged
Note 1: These bits are only used in Host mode; do not use in Device mode.
