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 ad-

dress. Otherwise, when this bit is cleared to 0, 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 ac-

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

Bit 2~Bit 6 Reserved bit

R/W

This bit is used to control whether the USB interrupt is output to the MCU in NAK respon.
