Page 0 / Register 4: PLL Programming Register B
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7 – D2 R/W 000001 PLL J Value
000000: Reserved, do not write this sequence
000001: J = 1
000010: J = 2
000011: J = 3
…
111110: J = 62
111111: J = 63
D1 – D0 R/W 00 Reserved, write only zeros to these bits
Table 1. Page 0 / Register 5: PLL Programming Register C
(1)
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7-D0 R/W 00000000 PLL D(13:6) – Eight most significant bits of a 14-bit unsigned integer valid values for D are from
zero to 9999, represented by a 14-bit integer located in Page-0/Reg-5-6. Values should not be
written into these registers that would result in a D value outside the valid range.
(1) When programming PLL D value, register 5 should always be written first, immediately followed by register 6. Even if only the MSB or
LSB of the value changes, both registers should be written.
Page 0 / Register 6: PLL Programming Register D
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7 – D2 R/W 00000000 PLL D(5:0) – Six least significant bits of a 14-bit unsigned integer valid values for D are from
zero to 9999, represented by a 14-bit integer located in Page-0/Reg-5-6. Values should not be
written into these registers that would result in a D value outside the valid range.
D1-D0 R 00 Reserved. Do not write to these bits.
Page 0 / Register 7: DAC Datapath Setup Register
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7 R/W 0 Fsref setting
0: Fsref = 48-kHz
1: Fsref = 44.1-kHz
D6 R/W 0 Reserved. Only write zero to this bit.
D5 R/W 0 DAC Dual Rate Control 0: DAC dual rate mode is disabled 1: DAC dual rate mode is enabled
D4 – D3 R/W 00 Left DAC Datapath Control
00: Left DAC datapath is off (muted)
01: Left DAC datapath plays left channel input data
10: Left DAC datapath plays right channel input data
11: Left DAC datapath plays mono mix of left and right channel input data
D2 – D1 R/W 00 Right DAC Datapath Control
00: Right DAC datapath is off (muted)
01: Right DAC datapath plays right channel input data
10: Right DAC datapath plays left channel input data
11: Right DAC datapath plays mono mix of left and right channel input data
D0 R/W 0 Reserved. Only write zero to this register.
