Note: All FIFOs for each endpoint is enabled after a reset.
Stall Control Bit
When this bit is set, the Endpoint returns a STALL handshake whenever
it receives an IN or OUT token.
Data Toggle Bit
– Endpoint IN Case
The state of this bit determines the type of data packet (0=DATA0 or
1=DATA1) that will be sent during the next IN transaction. This bit is
managed by the USB SIE. It is only toggled when an ACK is properly
received during the IN transaction. In some cases it may be necessary
for firmware to clear this bit. In this case, see the Important Notes
section at the end of this data sheet.
– Endpoint OUT Case
The state of this bit indicates the type of data packet PID that the USB
SIE expects to receive with the next OUT transaction (0=DATA0,
1=DATA1). If the Data Toggle for the next OUT transaction received is
not as expected, the USB SIE assumes the host is retransmitting the
last packet. In this case, an ACK is sent but no interrupt is generated
since the original transmission of the packet was OK. This bit is
managed by the USB SIE. It is only toggled when an OUT packet is
properly received. In some cases it may be necessary for firmware to
clear this bit. In this case, see the Important Notes section at the end of
this data sheet.
Important notes:
1. Disabling and enabling the USB SIE using the USBEN bit the UCTL
register clears the TOGGLE bit for both directions of all endpoints.
2. Revision A silicon: See the Important Notes section at the end of the
data sheet that explains the workaround for clearing this data toggle bit.
3. Revision B silicon: Disabling and Enabling the selected FIFO using
the ENABLE bit in this register clears the data toggle bit for the selected
endpoint's FIFO.
