Virtex-II Pro-X RocketIO- Where is the second bit of RXCPI?


General Description:  

In the RocketIO-X Transceiver User Guide (UG035 v1.5) the memory map on p. 148, Table C-2 shows RXCPI to be a single bit in the register at address 0x0A. However, on p.158 RXCPI is described as being a 2 bit number. 


Where is the second bit of RXCPI?


Following is the mapping of RXCPI[1:0] to Table C-2 


RXCPI<1> = RXCPGAIN (Bit7 of Reg 0xB in table C-2) 

RXCPI<0> = RXCPI (Bit1 of Reg 0xA in table C-2).
