USB: EP_STALL_ARM Register
Offset: 0x68
Description
Device: this bit must be set in conjunction with the STALL bit in the buffer control register to send a STALL on EP0.
The device controller clears these bits when a SETUP packet is received because the USB spec requires that a
STALL condition is cleared when a SETUP packet is received.
