Description

Adr_set

R/W

This bit is used to configure the USB SIE to automatically change the device address with

the value of the Address+Remote_WakeUp Register (42H).

When this bit is set to 1 by F/W, the USB SIE will update the device address with the value

of the Address+Remote_WakeUp Register (42H) after the PC Host has successfully read

the data from the device by the IN operation. The USB SIE will clear the bit after updating

the device address.

Otherwise, when this bit is cleared to

²0², the USB SIE will update the device address im-

mediately after an address is written to the Address+Remote_WakeUp Register (42H).

F0_Err

R/W

This bit is used to indicate when there are some errors that occurred when the FIFO0 is

accessed.

This bit is set by the USB SIE and cleared by F/W.

¾¾

Unused bit, read as

²0²

MNI

R/W

This bit is for masking the NAK interrupt when MNI=

²1², the default value=²0²
