Description

When set, the ATX is in transparent UART mode. The default value of this
bit depends on the SERVICE_N pin. On reset, if SERVICE_N = HIGH, the
reset value of UART_EN = 0; if SERVICE_N = LOW, the reset value of
UART_EN = 1.
When set and when in suspend mode, pin OE_N/INT_N becomes an
output and is asserted when an interrupt occurs.
This bit has two functions:
For an A-device, this bit works as BDIS_ACON_EN. It enables the A-device
to connect if the B-device disconnect is detected; see
0 — DP pull-up resistor is controlled by the DP_PULLUP bit in the OTG
Control register.
1 — DP pull-up resistor will connect on the B-device disconnect.
For a B-device, this bit works as ACON_BSE0_EN. It enables the B-device
to drive SE0 on DP and DM, if the A-device connect is detected.
0 — B-device will stop driving SE0.
1 — B-device will start to drive SE0, if the A-device connect is detected.
When set, the ATX is in transparent general-purpose buffer mode.
0 — VP_VM mode
1 — DAT_SE0 mode
Sets the transceiver in low-power mode.
0 — Active-power mode
1 — Low-power mode (differential receiver is disabled if SPEED = 1)
Set the rise time and the fall time of the transmit driver in USB modes.
0 — Low-speed mode
1 — Full-speed mode
