Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 31-8 Unimplemented: Read as ‘0’
bit 7 DPPULUP: D+ Pull-Up Enable bit
1 = D+ data line pull-up resistor is enabled
0 = D+ data line pull-up resistor is disabled
bit 6 DMPULUP: D- Pull-Up Enable bit
1 = D- data line pull-up resistor is enabled
0 = D- data line pull-up resistor is disabled
bit 5 DPPULDWN: D+ Pull-Down Enable bit
1 = D+ data line pull-down resistor is enabled
0 = D+ data line pull-down resistor is disabled
bit 4 DMPULDWN: D- Pull-Down Enable bit
1 = D- data line pull-down resistor is enabled
0 = D- data line pull-down resistor is disabled
bit 3 VBUSON: VBUS Power-on bit
1 = VBUS line is powered
0 = VBUS line is not powered
bit 2 OTGEN: OTG Functionality Enable bit
1 = DPPULUP, DMPULUP, DPPULDWN and DMPULDWN bits are under software control
0 = DPPULUP, DMPULUP, DPPULDWN and DMPULDWN bits are under USB hardware control
bit 1 VBUSCHG: VBUS Charge Enable bit
1 = VBUS line is charged through a pull-up resistor
0 = VBUS line is not charged through a resistor
bit 0 VBUSDIS: VBUS Discharge Enable bit
1 = VBUS line is discharged through a pull-down resistor
0 = VBUS line is not discharged through a resistor
