Unused. Read = 0; Write = don’t care.
CLRDT: Clear Data Toggle.
Write: Software should write ‘1’ to this bit to reset the IN Endpoint data toggle to ‘0’.
Read: This bit always reads ‘0’.
STSTL: Sent Stall
Hardware sets this bit to ‘1’ when a STALL handshake signal is transmitted. The FIFO is
flushed, and the INPRDY bit cleared. This flag must be cleared by software.
SDSTL: Send Stall.
Software should write ‘1’ to this bit to generate a STALL handshake in response to an IN
token. Software should write ‘0’ to this bit to terminate the STALL signal. This bit has no
effect in ISO mode.
FLUSH: FIFO Flush.
Writing a ‘1’ to this bit flushes the next packet to be transmitted from the IN Endpoint FIFO.
The FIFO pointer is reset and the INPRDY bit is cleared. If the FIFO contains multiple pack-
ets, software must write ‘1’ to FLUSH for each packet. Hardware resets the FLUSH bit to ‘0’
when the FIFO flush is complete.
UNDRUN: Data Underrun.
The function of this bit depends on the IN Endpoint mode:
Isochronous: Set when a zero-length packet is sent after an IN token is received while bit
INPRDY = ‘0’.
Interrupt/Bulk: This bit is not used in these modes and will always read a '0'.
This bit must be cleared by software.
FIFONE: FIFO Not Empty.
0: The IN Endpoint FIFO is empty.
1. The IN Endpoint FIFO contains one or more packets.
INPRDY: In Packet Ready.
Software should write ‘1’ to this bit after loading a data packet into the IN Endpoint FIFO.
Hardware clears INPRDY due to any of the following:
1. A data packet is transmitted.
2. Double buffering is enabled (DBIEN = ‘1’) and there is an open FIFO packet slot.
3. If the endpoint is in Isochronous Mode (ISO = ‘1’) and ISOUD = ‘1’, INPRDY will read ‘0’
until the next SOF is received.
An interrupt (if enabled) will be generated when hardware clears INPRDY as a result
of a packet being transmitted.
