USB wrapper configuration registers.
SRP_SESSEND_OVERRIDE | This bit is used to enable the software over-ride of srp session end signal. 1’b0: the signal is controlled by the chip input, 1’b1: the signal is controlled by the software. |
SRP_SESSEND_VALUE | Software over-ride value of srp session end signal. |
PHY_SEL | Select internal external PHY. 1’b0: Select internal PHY, 1’b1: Select external PHY. |
DFIFO_FORCE_PD | Force the dfifo to go into low power mode. The data in dfifo will not lost. |
