PIT Delay Function in C: Precise Timing with Programmable Interval Timer

The function `pit_delay` delays the program execution by a specified amount of time using the Programmable Interval Timer (PIT). It takes two parameters: \n\n - `pit_ch`: The PIT channel to use for the delay. This can be either 0 or 1.\n - `MSEC_TO_COUNT(time, PIT_SOURCE_CLOCK)`: This macro converts the desired delay time in milliseconds (`time`) to the corresponding number of PIT counter ticks based on the PIT source clock frequency.\n\nHere's an example usage of the `pit_delay` function:\n\nc\npit_delay(0, MSEC_TO_COUNT(1000, PIT_SOURCE_CLOCK));\n\n\nThis code will delay the program execution by approximately 1000 milliseconds (1 second) using PIT channel 0.
