Group 2 General-Purpose Registers
4-5
MSIZE
Symbol Size
R/W [2:0]
This value indicates the size of symbols:
0b000 = 1 bit
0b001 = 2 bit
0b010 = 3 bit
0b011 = 4 bit
0b100 = 5 bit
0b101 = 6 bit
0b110 = 7 bit
0b111 = 8 bit.
The reset value is 0b101
4.1.3 Register 2
RES

7
This bit is reserved.
FDEL
FIFO Delay
R/W [6:0]
This parameter indicates the FIFO delay value in the
Gray Code. Writing to this location loads the ICLK
address counter with 0 and the OCLK-driven address
counter to the FDEL value. If the FIFO is automatically
reset, the L64777 also uses this value for the
OCLK-driven address. The reset value is 0b110 0000.
4.1.4 Register 3
SMAG
Sign Magnitude
R/W 7
When this bit is 0, the L64777 outputs a two’s
complement at the Nyquist filter. When this bit is 1, the
L64777 inverts the sign bit and the output sign magnitude
representation. The reset value is 0.
