CFIFO Port Access Pipe Specification 
Specifies the pipe number for reading or writing data 
through the CFIFO port.  
0000: DCP 
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 
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 and 1 can be written.
