Description

Analog Audio PLL control Register

Fields

DIV_SELECT

This field controls the PLL loop divider. Valid range for DIV_SELECT divider value: 27~54.

POWERDOWN

Powers down the PLL.

ENABLE

Enable PLL output

BYPASS_CLK_SRC

Determines the bypass source.

0 (REF_CLK_24M): Select the 24MHz oscillator as source.

1 (CLK1): Select the CLK1_N / CLK1_P as source.

BYPASS

Bypass the PLL.

PFD_OFFSET_EN

Enables an offset in the phase frequency detector.

POST_DIV_SELECT

These bits implement a divider after the PLL, but before the enable and bypass mux.

0 (POST_DIV_SELECT_0): Divide by 4.

1 (POST_DIV_SELECT_1): Divide by 2.

2 (POST_DIV_SELECT_2): Divide by 1.

LOCK

1 - PLL is currently locked. 0 - PLL is not currently locked.
