3 to 0 CURPIPE[3:0] 0000 R/W CFIFO Port Access Pipe Specification
Specifies the pipe number using which data is read
or written through the CFIFO port.
0000: DCP
0001: Pipe 1
0010: Pipe 2
0011: Pipe 3
0100: Pipe 4
0101: Pipe 5

0111: Pipe 7
1000: Pipe 8
1001: Pipe 9
Other than above: Setting prohibited
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 to 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 until the access is
completed. Then, the modification becomes effective
thus enabling continuous access.
Note: * Only 0 can be read.
