16 and 24 bit read and write operations between PIC18F45K22 and ADE7763

I have already performed an 8 bit read and write operation using SPI interface between PIC18F45K22 and ADE7763. However, I am unable to correctly perform a 16 or 24 bit read or write operation between both. What I wanted to know is whether any changes need to be made in the mode registers or whether any calibration needs to be done to perform 16 and 24 bit read and write operations on ADE energy registers? And also, do we need to write dummy data to ADE registers for every byte that we read (assuming its a 16 or 24 bit register like VRMS/MODE registers)?
