Description
Adr_set
R/W
This bit is used to configure the SIE to automatically change the device address with
the value of the Address+Remote_WakeUp Register (42H).
Whenthisbitissetto 1 byF/W,theSIEwillupdatethedeviceaddresswiththevalue
of the Address+Remote_WakeUp Register (42H) after the PC Host has successfully
readthe datafrom the deviceby the IN operation.The SIE willclearthe bit after updat-
ing the device address. Otherwise, when this bit is cleared to 0 , the SIE will update
the device address immediately after an address is written to the Address+Re-
mote_WakeUp Register (42H)
Default 0
F0_Err
R/W
ThisbitisusedtoindicatethatsomeerrorshaveoccurredwhenaccessingtheFIFO0.
This bit is set by SIE and cleared by F/W.
Default 0
Out
R/W
This bit is used to indicate that an OUT token (except for the OUT zero length) has
been received. The F/W clear the bit after the OUT data has been read. This bit will
also be cleared by the SIE after the next valid SETUP token is received.
Default 0
IN
R
This bit is used to indicate that the current signal the USB is receiving from the PC
Host is IN token.
NAK
R
This bit is used to indicate that the SIE is transmitting NAK signal to the Host in re-
sponse to the PC Host IN or OUT token.
CRC_ERR
R/W
This bit is used to indicate there are CRCerror (bit=1). Firmware must do something to
save the device and keep it in good condition.
This bit is set by SIE and cleared by F/W.
EOT
R
End of transaction flag, normal status is 1. If suspend= 1 line & EOT= 0 indicates that
something is wrong in the USB Interface. Firmware in-charge must do something to
save the device and keep it in good condition.
NMI
R/W
This bit is used to control whether the USB interrupt is output to the MCU in NAK re-
sponse to the PC Host IN or OUT token.
1: has only USB interrupt, data is transmitted to the PC host or data is received from
the PC Host
0: always has USB interrupt if the USB accesses FIFO0
Default 0
