The peripheral clock is based on a low-frequency/low-power 32 kHz secondary oscillator
that can be used with an external watch crystal. The peripheral clock is only available for
driving Timer and associated noise filter operation. It is not supported for other
peripherals. The dedicated peripheral clock source allows Timer operation when the
device is in STOP Mode.
Table 169
The Oscillator Control Register (OSCCTL0) enables/disables the various oscillator
circuits, enables/disables the failure detection/recovery circuitry, and selects the primary
oscillator, which becomes the system clock.
The Oscillator Control 0 Register must be unlocked before writing. Writing the two step
sequence
is locked at successful completion of a register write to the OSCCTL0.
It is possible to disable the clock failure detection circuitry as well as all functioning
clock sources. In this case, the Z8 Encore! XP F1680 Series device ceases functioning
and can only be recovered by Power-on reset.
