2.14 Pipe configuration register

The PIPE1-7 settings should be set using the PIPESEL, PIPECFG, PIPEBUF, PIPEMAXP, PIPEPERI, and

PIPExCTR

registers.

After selecting the pipe using the PIPESEL register, set the functions of the pipe using the PIPECFG, PIPEBUF,

PIPEMAXP

and PIPEPERI registers. The PIPExCTR register can be set separately from the pipe selection specified

with the PIPESEL register, with no relation between them.

For an H/W reset, S/W reset, USB bus reset, and when shifting to the low-power sleep state, the pertinent bits for

not only the selected pipe, but all of the pipes are initialized.
