Description

DPLL_NUM

Contains the ratio between the CLK and the audio clock rate once the DPLL has acquired lock.

This value is latched on reading the LSB, so register 66 must be read first to acquire the latest DPLL value and

avoid data tearing. The value is latched on LSB because the DPLL number can change as the I2C transactions are

performed.
