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