Introduction
The device includes a range of utility features for securing the application in critical
situations (for example, in case of a power brown-out), and reducing the number of external
components. An overview is shown in

Phase locked loop
If the clock frequency input to the PLL is in the range 2 to 4 MHz, the PLL can be used to
multiply the frequency by two to obtain an f
byte. If the PLL is disabled, then f
The PLL is not recommended for applications where timing accuracy is required.
