Implementation of the clock module for the CC26xx and CC13xx.
The software clock uses the facilities provided by the AON RTC driver
void clock_delay_usec | ( | uint16_t | dt | ) |
void clock_init | ( | void | ) |
Initialize the clock library.
This function initializes the clock library and should be called from the main() function of the system.
Initialize the clock library.
We initialise the SysTick to fire 128 interrupts per second, giving us a value of 128 for CLOCK_SECOND
We also initialise GPT0:Timer A, which is used by clock_delay_usec(). We use 16-bit range (individual), count-down, one-shot, no interrupts. The prescaler is computed according to the system clock in order to get 1 tick per usec.
