TXFLG1
Initial Value
USB TX FIFO 1 Flag/Control Register
Bit[7:4]

Reserved
Bit3
T1EPE
0b
R/W
This bit is used to enable/disable the endpoint 1
1: Enable endpoint 1
0: Disable, the corresponding endpoint does not respond to a valid IN Token
Reset source: Hardware reset or USB reset
Bit2
T1SEQC
0b
W
The data sequence of each transmitted data packet is controlled by hardware
and is toggled after receiving ACK from host. The F/W can reset the data
sequence by writing “1” to T1SEQC for resetting the next transmitting data
sequence on endpoint 1. Write “0” to no effect.
Read this bit will always get value with “0”
Reset source: Hardware reset or USB reset
Bit1
STLT1
0b
R/W
Pipe 1 stall bit
, this bit is used to stall the pipe 1. STL1 is set by SETUP
command - SetFeature (ENDPOINT_HALT) and STL1 is reset by SETUP
command - ClearFeature (ENDPOINT_HALT).
0: responds ACK, NAK or not respond to IN1
1: STLT1 bit is used to stall the pipe 1 IN token. SIE will respond STALL to
Host IN token as long as STLT1 bit is set
Reset source: Hardware reset or USB reset
Bit0
T1FULL
0b
R/W
TXDAT1 FIFO full status bit
. F/W writes “1” to set H/W FIFO pointer.
Clear to “0” by H/W after receiving ACK form host.
0: Empty
1: Full
Reset Source: Hardware reset, USB reset
