Description
FREQ0 REG
32 Bits
Frequency Register 0. This defines
the output frequency, when
FSELECT = 0, as a fraction of the
MCLK frequency.
FREQ1 REG
32 Bits
Frequency Register 1. This de-
fines the output frequency, when
FSELECT = 1, as a fraction of the
MCLK frequency.
PHASE0 REG
12 Bits
Phase Offset Register 0. When
PSEL0 = PSEL1 = 0, the contents
of this register are added to the out-
put of the phase accumulator.
PHASE1 REG
12 Bits
Phase Offset Register 1. When
PSEL0 = 1 and PSEL1 = 0, the
contents of this register are added
to the output of the phase
accumulator.
PHASE2 REG
12 Bits
Phase Offset Register 2. When
PSEL0 = 0 and PSEL1 = 1, the
contents of this register are added
to the output of the phase
accumulator.
PHASE3 REG
12 Bits
Phase Offset Register 3. When
PSEL0 = PSEL1 = 1, the contents
of this register are added to the out-
put of the phase accumulator.
