Enables fast power for SPKR output
Enables fast power for HPL output
Enables fast power for HPR output
Enables fast power for OUT3 output
Enables fast power for OUT4 output
Defines clock division ratio for Hi-fi block: 000=f;
001=f/2; ... ; 111=f/8
Defines clock division ratio for voice DAC clock:
0000=f; 0001=f/2; … ; 1111=f/16
Selects between PLL clock and External clock
Sets AUXADC clock divisor: 000=f/16; 001=f/12;
010=f/8; 011=f/6; 100=f/4; 101=f/3; 110=f/2; 111=f
Clock doubler for MCLKB
Clock doubler for MCLKA
Selects between MCLKA and MCLKB (N.B. On
power-up clock must be present on MCLKA and
must be active for 2 clock cycles after switching to
MCLKB)
PLL integer division control (must be set between 5-
12 for integer N mode)
Allows PLL operation with low frequency input
clocks (< 8.192MHz)
Sigma Delta Modulator enable. Allows fractional N
division
Enables input clock to PLL to be divided by 2 or 4.
Use if input clock is above 14.4MHz
Controls division mode when DIVSEL is high. 0 = div
by 2, 1= div by 4.
