CFIFO Port Access Direction When DCP is Selected
0: Reading from the buffer memory is selected 
1: Writing to the buffer memory is selected 
After writing to this bit with the DCP being a selected 
pipe, read this bit to check that the written value 
agrees with the read value before proceeding to the 
next process. 
Even if an attempt is made to modify the setting of 
this bit 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. 
Set this bit and the CURPIPE bits simultaneously.

This bit is always read as 0. The write value should 
always be 0.
