GL640USB, GL640USB-A
0:
the ping-pong FIFO is used for end1
DMATXEN
-
enable DMA/EPP engine to access data into TXFIFO
DMARXEN
-
enable DMA/EPP engine to move data from RXFIFO into external
Device
TXNULL
-
Set this bit to transmit a zero-byte data on endp1
This bit will be cleared by hardware automatically.
TX64ONLY
-
Transmit 64-byte packet only
When this bit is set, data left in FIFO will not be sent if it is not
64 bytes.
Note: When LINKFF is set and LINKDIR is gonna to change, LINKFF should be cleared to ‘0’ first and
then change LINKDIR and set LINKFF again.

CTLTXEN
CTLTXEN -
enable endpoint 0 transmitting
This bit is cleared by hardware when CTLTX interrupt is set.
CTLRXDIS
-
disable endpoint 0 receiving
DTXEN
-
turn on this bit to enable endpoint 1 data packet transmission.
If LINKFF=1, it indicates the TXFIFO0 is ready.
This bit is cleared by hardware when DATATX interrupt is set.
DRXDIS
-
disable RXFIFO receiving
If this bit is set, NAK will be responded to the OUT token.
Data in RXFIFO is kept unchanged.
If LINKFF=1, this bit means the TXFIFO1 is ready.
STSTXEN -
enable endpoint 3 transmitting
This bit is cleared by hardware when STSTX interrupt is set.
TXFFRST
-
reset TXFIFO, cleared by hardware itself.
RXFFRST -
reset RXFIFO, cleared by hardware itself
FF0RST
-
reset CTL/STS FIFO, cleared by hardware itself
FF0DAT
