5.2.7
This register holds the user supplied reference pattern of 8, 16, 24, or 32 bits (see the ADParam_Psize parameter).
The first byte of this pattern is always stored in the byte at address A[4:0] = 10011. If used, the 2
address A[4:0] = 10100, the 3
The MSB bit of the reference pattern is always bit 7 of address 10011.
Comparing the demodulated data, the first bit received of the last word is compared with bit 7 (the MSB) of byte
address 10011. The last bit received is compared with bit 0 (the LSB) in the Pattern register.
