32-BIT TIMERS
TIMER OPERATION GUIDELINES
The block diagram in Figure 11-2 shows how the 32-bit timers are configured in the S3C4510B. The following
guidelines apply to timer functions.
— When a timer is enabled, it loads a data value to its count register and begins decrement the count register
— When the timer interval expires, the associated interrupt is generated. The base value is then reloaded and
— If a timer is disabled, you can write a new base value into its registers.
— If the timer is halted while it is running, the base value is not automatically re-loaded.
