System Clock Selection
The Z16FMC device uses three possible user-selectable clocking schemes:
•
•
•
In addition, Z16FMC devices contain clock failure detection and recovery circuitry, allow-
ing continued operation despite a failure of the primary oscillator.
The on-chip system clock frequency is reduced through a clock divider allowing reduced
dynamic power dissipation. Flash memory is powered down during portions of the clock
period when running slower than 10 MHz.
This section explains the logic used to select the system clock, divide down the system
clock and handle oscillator failures. A description of the specific operation of each oscilla-
tor is outlined elsewhere in this document. See
the
on page 282.
The oscillator control block selects from the available clocks. Table 165 details each clock
source and its usage.
