Figure B-18. USB Control Register

Controls various USB functions. This register is read/write by the MCU only.

Table B-46. USB Control Register

MO

A value of 1 means: MCU has completed boot sequence and is ready to respond to USB commands

DI

A value of 1 means: Disconnect CONFIG device and enumerate again using the downloaded MCU configuration

BB

A value of 1 means: After reset boot from MCU RAM, 0 = after reset boot from

MCU ROM

RW

A value of 1 means: Enables remote wake-up capability, 0 = disables remote wake-up capability

INT

Active interrupt for the 8051 MCU

ISE

Current interrupt is for a SETUP token

IIN

Current interrupt is for an IN token sent with a non zero length data stage

IOU

Current interrupt is for an OUT token received with a non zero length data stage

BY

Busy bit. A value of 1 means: MCU is busy processing a command. USB interface responds with NAK to further IN/OUT requests from the host until MCU clears this bit.

ER

Error in the current SETUP transaction. Generate STALL condition on EP0.
