1. PLL operation
2. PLL standards
Performing this DSP operation using PLL requires satisfaction of the following operation.
When using PLL, set the PSTOP pin at “H” for 1 sec or more for a reset, then at “L”, and wait for lockup time
or more time.
(1) Take enough time for MCLK input and for lockup at the PLL operation state with PSTOP equal to "L".
(2) Hold the DSP reset state until PLL is locked. (XRST = “L”)
(3) When PLL is locked, the “L” pin goes “H”.
(4) After PLL has been locked, change XRST from “L” to “H” to start DSP operation.
