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.
