Function Documentation
◆ timer0_1ms_delay()
| void timer0_1ms_delay | ( | ) |
Executes a 1 millisecond delay using Timer0.
Starts Timer0 and waits for the overflow flag (TF0) to be set, indicating that the configured 1ms time interval has elapsed. The timer is configured by timer0_1ms_delay_init() with the appropriate reload values for the system clock frequency.
- Note
- This is a blocking function that waits in a polling loop until the timer overflow occurs.
- Timer0 must be initialized with timer0_1ms_delay_init() before calling this function.

◆ timer0_1ms_delay_init()
| void timer0_1ms_delay_init | ( | ) |
Initializes Timer0 for 1 millisecond delay using precalculated ticks.
- Note
- Must be called before using timer0_1ms_delay() to ensure correct timer configuration for the current system clock settings.
- Disables Timer0 interrupt during initialization to prevent unwanted interrupt service routine execution.
