Note 16: The delay for the sleep voltage monitor output, RESET, to go high after V
Note 17: It is gated by an AND function with three inputs—the external RESET signal, the internal DV
Note 18: If FLLE = 0, the internal signal CRDY is not generated by the FLL block and INT or INT are deasserted.
Note 19: CRDY is used as an interrupt signal to inform the µC that the high-frequency clock has started. Only valid if FLLE = 1.
