“res” is reserved bit for the future use, the default state of those is ‘0.’
CP is the parity bit of data payload. BU7961GUW adds an odd parity on CP of the high-speed channel data.
・When the number of ‘H’ bits in parallel data is even, CP bit is ‘H.’
・When the number of ‘H’ bits in parallel data is odd, CP bits is ‘L.’
