When this bit is set to ‘1’, D+ and D- pin will be driven to low so that no connect
will be detected on the host side.

EP0RX
This register is the main USB interrupt flag for endpoint 0 and power management. The firmware
detects endpoint 0 transaction via EP0RX and EP0TX. If firmware can’t handle the received endpoint 0
control data, then firmware should write ‘1’ to S_CTLRX and EP0RX. By this, the interrupt will redirect to
the external DMA interrupt and the CTLRX bit of USBFLG register will be set. For power management,
when a USB suspend is detected, the SUSPD bit will be set to ‘1’. If the USB host put the bus to ‘K’ state
during suspend, then the RESUME bit will be set to ‘1’. If a remote-wake-up event is detected, then the
WAKEUP bit will be set to ‘1’.
All those interrupt status bits can be written ‘1’ to clear.
EP0RX
-
Endpoint 0 receives a data packet.
EP0TX
-
Endpoint 0 transmits a data packet completely.
SUSPD
-
USB suspend detected
RESUME -
USB resume detected
WAKEUP- remote-wake-up event is detected during suspend state
The event is
DMA mode:
WAKEVT bit is set
EPP mode: INT_ pin is asserted low
S_CTLRX- Write 1 to set CTLRX bit of USBFLG
All the data in endp0/endp3 FIFO are left unchanged.
