CS42418
5.8
OMCK/PLL_CLK Ratio (address 07h) (Read Only)
5.8.1
OMCK/PLL_CLK RATIO (RATIOX)
Default = sixth
Function:
This register allows the user to find the exact absolute frequency of the recovered MCLK coming from
the PLL. This value is represented as an integer (RATIO7:6) and a fractional (RATIO5:0) part. For
example, an OMCK/PLL_CLK ratio of 1.5 would be displayed as 60h.
5.9
Clock Status (address 08h) (Read Only)
5.9.1
SYSTEM CLOCK SELECTION (ACTIVE_CLK)
Default = x
0 - Output of PLL
1 - OMCK
Function:
This bit identifies the source of the internal system clock (MCLK).
5.9.2
PLL CLOCK FREQUENCY (PLL_CLKX)
Default = xxxh
Function:
The CS42418 will auto-detect the ratio between the OMCK and the recovered clock from the PLL,
which is displayed in register 07h. Based on this ratio, the absolute frequency of the PLL clock can
be determined, and this information is displayed according to the following table. If the absolute fre-
quency of the PLL clock does not match one of the given frequencies, this register will display the
closest available value.
NOTE: These bits are set to ‘111’b when the FRC_PLL_LK bit is ‘1’b.
