23.3.31 Pipe Window Select Register (PIPESEL)
PIPESEL is a register that selects the pipe to be used among PIPE1 to PIPE7. After selecting the
pipe, functions of the pipe should be set using PIPECFG, PIPEBUF, PIPEMAXP, and PIPEPERI.
PIPEnCTR can be set regardless of the pipe selection in PIPESEL.
For a power-on reset, a software reset and a USB bus reset, the corresponding bits for not only the
selected pipe but all of the pipes are initialized.
This register is initialized by a power-on reset or a software reset.
