2. Write to the Timer High and Low Byte Registers to set the starting count value.
3. Write to the Timer Reload High and Low Byte Registers to set the Reload value.
4. If desired, enable the timer interrupt and set the timer interrupt priority by writing to
5. If using the Timer Output function, configure the associated GPIO port pin for the
6. Write to the Timer Control Register to enable the timer and initiate counting.
In ONE-SHOT mode, the system clock always provides the timer input. The timer period
is given by the following equation:
CONTINUOUS Mode
In CONTINUOUS mode, the timer counts up to the 16-bit Reload value stored in the
Timer Reload High and Low Byte Registers. The timer input is the system clock. Upon
reaching the Reload value, the timer generates an interrupt, the count value in the Timer
High and Low Byte Registers is reset to
Output alternate function is enabled, the Timer Output pin changes state (from Low to
High or from High to Low) upon timer Reload.
Follow the steps below for configuring a timer for CONTINUOUS mode and initiating the
count:
1. Write to the Timer Control Register to:
