D+ Pull-down Enable (Bit 7)
The D+ Pull-down Enable bit enables or disables a pull-down
resistor on the OTG D+ data line.
1: OTG D+ dataline pull-down resistor enabled
0: OTG D+ dataline pull-down resistor disabled
D– Pull-down Enable (Bit 6)
The D– Pull-down Enable bit enables or disables a pull-down
resistor on the OTG D– data line.
1: OTG D– dataline pull-down resistor enabled
0: OTG D– dataline pull-down resistor disabled
OTG Data Status (Bit 2)
The OTG Data Status bit is a read only bit and indicates the TTL
logic state of the OTG VBus pin.
1: OTG VBus is greater than 2.4 V
0: OTG VBus is less than 0.8 V
ID Status (Bit 1)
The ID Status bit is a read only bit that indicates the state of the
OTG ID pin on Port A.
1: OTG ID Pin is not connected directly to ground (>10K ohm)
0: OTG ID Pin is connected directly ground (< 10 ohm)
VBUS Valid Flag (Bit 0)
The VBUS Valid Flag bit indicates whether OTG VBus is greater
than 4.4 V. After turning on VBUS, firmware should wait at least
10 µs before this reading this bit.
1: OTG VBus is greater then 4.4 V
0: OTG VBus is less then 4.4 V
Reserved
All reserved bits must be written as ‘0’.
