Description
Set to logic 1 when the DP voltage is higher than carkit interrupt
threshold V
0 — Voltage on DP is below V
1 — Voltage on DP is above V
reserved
Indicates the status of pin ID:
0 — ID pin is not floating
1 — ID pin is floating.
DP and DM SE1 detected. The period of SE1 needed is controlled by
TMR_SE1 bits.
0 — SE1 is not detected
1 — SE1 is detected.
Indicates the status of pin ID:
0 — ID pin is not grounded
1 — ID pin is grounded.
DP single-ended receiver output:
0 — LOW
1 — HIGH.
