Z8 Encore! XP
user-selectable:
On-chip precision trimmed RC oscillator
External clock drive
On-chip low power Watchdog Timer oscillator
In addition, Z8 Encore! XP F0823 Series devices contain clock failure detection and
recovery circuitry, allowing continued operation despite a failure of the primary oscillator.
Operation
This chapter discusses the logic used to select the system clock and handle primary
oscillator failures. A description of the specific operation of each oscillator is outlined
elsewhere in this document.
System Clock Selection
The oscillator control block selects from the available clocks.
source and its usage.
Table 101. Oscillator Configuration and Selection
Clock Source
Characteristics
Internal Precision
• 32.8 kHz or 5.53 MHz
RC Oscillator
• ± 4% accuracy when trimmed
• No external components required
External Clock
• 0 to 20 MHz
Drive
• Accuracy dependent on external clock
source
Internal Watchdog
• 10 kHz nominal
Timer Oscillator
• ± 40% accuracy; no external
components required
• Very Low power consumption
PS024314-0308
F0823 Series devices uses three possible clocking schemes, each
Required Setup
• Unlock and write Oscillator Control
Register (OSCCTL) to enable and
select oscillator at either 5.53 MHz or
32.8 kHz
• Write GPIO registers to configure PB3
pin for external clock function
• Unlock and write OSCCTL to select
external system clock
• Apply external clock signal to GPIO
• Enable WDT if not enabled and wait
until WDT Oscillator is operating.
• Unlock and write Oscillator Control
Register (OSCCTL) to enable and
select oscillator
