USB Host Pipe registers
• 7-0 - FLEN7:0 - Frame Length
The value contained the data frame length transmited.
• 7-3 - Reserved
The value read from these bits is always 0. Do not set these bits.
• 2-0 - PNUM2:0 - Pipe Number
Select the pipe using this register. The USB Host registers ended by a X correspond then to this
number.
This number is used for the USB controller following the value of the PNUMD bit.
• 7 - Reserved
The value read from these bits is always 0. Do not set these bits.
• 6 - P6RST - Pipe 6 Reset
Set this bit to 1 and reset this bit to 0 to reset the Pipe 6.
• 5 - P5RST - Pipe 5 Reset
Set this bit to 1 and reset this bit to 0 to reset the Pipe 5.
• 4 - P4RST - Pipe 4 Reset
Set this bit to 1 and reset this bit to 0 to reset the Pipe 4.
• 3 - P3RST - Pipe 3 Reset
Set this bit to 1 and reset this bit to 0 to reset the Pipe 3.
• 2 - P2RST - Pipe 2 Reset
Set this bit to 1 and reset this bit to 0 to reset the Pipe 2.
