Filter Type
Clock based filter is used. The filter delay is proportional to PCLK period as
the following equations.
Filter Delay = T_PCLK * 64
If PCLK has 25MHz, then the filter delay has about 16us.
Delay cell based filter is used. The filter delay varies on the operating
conditions, like voltage, temperature, etc.
The nominal delay is about 120ns.
This type of filter must be selected when the PCLK has to be stopped, as like
as stop mode etc.
