Command error for device request interface. Used to indicate to the endpoint controller
that an error has been encountered during class or vendor specific device request or
SYNCH_FRAME command processing. This command bit is write only and always
returns 0 when read.
Result of Request
Processed device request successfully
Error processing the request
Busy processing the request
Note: CMD_OVER and CMD_ERR have to be written simultaneously. The CMD_OVER
and CMD_ERR bits control the status stage response for vendor and class specific
requests.
Command over for device request interface. Used to indicate to the endpoint controller
that processing of a class or vendor specific device request or SYNCH_FRAME
command has been completed by the user. This command bit is write only and always
returns 0 when read.
Note: CMD_OVER and CMD_ERR have to be written simultaneously. The CMD_OVER
and CMD_ERR bits control the status stage response for vendor and class specific
requests.
CRC error generation enable. This bit enables CRC error generation for debug and test
purpose. In order to use this feature, the DEBUG bit must be set. Enabling this bit causes
a CRC error on the next data packet transmitted. The CRC_ERR bit must be set again in
order to generate another CRC error. This bit only applies to IN transfers. This command
bit is write-only and always returns 0 when read.
1 CRC error generation if DEBUG = 1
0 default value
Reserved, should be cleared.
Endpoint 0 OUT FIFO level for interrupt. This field selects the FIFO level to generate an
OUT_LVL interrupt. The OUT_LVL interrupt is generated when the FIFO fills above the
selected level.
00 FIFO 25% Full
01 FIFO 50% Full
10 FIFO 75% Full
11 FIFO 100% Full
Endpoint 0 IN FIFO level for interrupt. This field selects the FIFO level to generate an
IN_LVL interrupt. The IN_LVL interrupt is generated when the FIFO falls below the
selected level.
00 FIFO 25% Empty
01 FIFO 50% Empty
10 FIFO 75% Empty
