bit 23 INCOMPTX: Incomplete TX Status bit (Device mode)
1 = For high-bandwidth Isochronous endpoint, a large packet has been split into 2 or 3 packets for
transmission but insufficient IN tokens have been received to send all the parts
0 = Normal operation
In anything other than isochronous transfers, this bit will always return 0.
NAKTMOUT: NAK Time-out status bit (Host mode)
1 = TX endpoint is halted following the receipt of NAK responses for longer than the NAKLIM setting
0 = Written by software to clear this bit
bit 22 CLRDT: Clear Data Toggle Control bit
1 = Resets the endpoint data toggle to 0
0 = Do not clear the data toggle
bit 21 SENTSTALL: STALL handshake transmission status bit (Device mode)
1 = STALL handshake is transmitted. The FIFO is flushed and the TXPKTRDY bit is cleared.
0 = Written by software to clear this bit
RXSTALL: STALL receipt bit (Host mode)
1 = STALL handshake is received. Any DMA request in progress is stopped, the FIFO is completely flushed
and the TXPKTRDY bit is cleared.
0 = Written by software to clear this bit
bit 20 SENDSTALL: STALL handshake transmission control bit (Device mode)
1 = Issue a STALL handshake to an IN token
0 = Terminate stall condition
This bit has no effect when the endpoint is being used for Isochronous transfers.
SETUPPKT: Definition bit (Host mode)
1 = When set at the same time as the TXPKTRDY bit is set, send a SETUP token instead of an OUT token
for the transaction. This also clears the Data Toggle.
0 = Normal OUT token for the transaction
bit 19 FLUSH: FIFO Flush control bit
1 = Flush the latest packet from the endpoint TX FIFO. The FIFO pointer is reset, TXPKTRDY is cleared and
an interrupt is generated.
0 = Do not flush the FIFO
bit 18 UNDERRUN: Underrun status bit (Device mode)
1 = An IN token has been received when TXPKTRDY is not set.
0 = Written by software to clear this bit.
ERROR: Handshake failure status bit (Host mode)
1 = Three attempts have been made to send a packet and no handshake packet has been received
0 = Written by software to clear this bit.
bit 17 FIFONE: FIFO Not Empty status bit
1 = There is at least 1 packet in the TX FIFO
0 = TX FIFO is empty
bit 16 TXPKTRDY: TX Packet Ready Control bit
The software sets this bit after loading a data packet into the FIFO. It is cleared automatically when a data
packet has been transmitted. This bit is also automatically cleared prior to loading a second packet into a dou-
ble-buffered FIFO.
