Undefined values are read from these bits. The write
value should always be 0.

R/W FIFO Port Access Pipe Specification
Specifies the pipe number of the pipe for access to
the DnFIFO port.
0000: Invalid
0001: Pipe 1
0010: Pipe 2
0011: Pipe 3
0100: Pipe 4
0101: Pipe 5
0110: Pipe 6
0111: Pipe 7
1000: Pipe 8
1001: Pipe 9
After writing to these bits, read these bits to check
that the written value agrees with the read value
before proceeding to the next process.
Do not set the same pipe number in the CURPIPE
bits in CFIFOSEL, D0FIFOSEL, and D1FIFOSEL.
Even if an attempt is made to modify the setting of
these bits during access to the FIFO buffer, the
current access setting is retained and access can be
continued after the setting of these bits are written
back.
Note: * Only 0 can be read and 1 can be written to.
