11
OTG_SE0_ This bit is used by the HC to send SE0 on remote connect.
EN
0 — No SE0 sent on remote connect detection
1 — SE0 (bus reset) sent on remote connect detection
Remark: This bit is normally set when the B-device goes into the
b_wait_acon state (recommended sequence:
LOC_CONN = 0 -> DELAY -> 50 µs -> OTG_SE0_EN = 1 ->
SEL_HC_DC = 0) and is cleared when it comes out of the
b_wait_acon state.
10
A_SRP_ This bit is for the A-device only. If set, the A_SRP_DET bit in the
DET_EN OtgInterrupt register will be set on detecting an SRP event.
0 — disable
1 — enable
9
A_SEL_ This bit is for the A-device to select a method for detecting the SRP
SRP
event (VBUS pulsing or data line pulsing).
0 — A-device responds to VBUS pulsing
1 — A-device responds to data line pulsing
8
SEL_HC_ This bit is used to select either the DC or the HC that interfaces with
DC
the transceiver.
0 — HC SIE is connected to the OTG transceiver
1 — DC SIE is connected to the OTG transceiver
7
LOC_
0 — disconnects the on-chip pull-down resistor on DM of the OTG
PULLDN_ port
DM
1 — connects the on-chip pull-down resistor on DM of the OTG port
6
LOC_
0 — disconnects the on-chip pull-down resistor on DP of the OTG
PULLDN_ port
DP
1 — connects the on-chip pull-down resistor on DP of the OTG port
5
A_RDIS_ This bit is for the A-device only. If set, the chip will automatically
LCON_EN enable its pull-up resistor on DP upon detecting a remote disconnect
event. If cleared, the DP pull-up is controlled by the LOC_CONN bit.
0 — disable
1 — enable
Remark: This bit is normally set when the A-device goes into the
a_suspend state and is cleared when it comes out of the a_suspend
state. The LOC_CONN bit must be set before clearing this bit.
