- * The PIT(Programmable Interval Timer) is a chip that consist of an oscillator
- * It's connected to IRQ0 and it can be configure at a user-defined rate
- * between 10.Hz to 1.1931 MHz. The PIT is the primary method used to implement
- * a system clock and for implement multitasking.
- * The PIT's internal clock(~1.1931 MHz) is fed through a frequency divider that

- * frequency divider:
- *  Channel 0: The most useful, it's output is connected to IRQ0
- *  Channel 1: It were used to control refresh rates on DRAM(RAMs with capacitors)
- *  Channel 2: Controls the PC speakers.
- * 
- * In our case, we will use only channel 0.
- * So we have to set up PIT at a frequency 'f', so it interrupts us at regular
- * intervals. We'll set the frequency to 100Hz(once every 10 ms); to do this
- * we'll send the PIT a divisor that will be divided for it's input frequency.
- * E.g. -> divisor = 1193180 Hz(1.1931MHz) / 100 Hz
- * 
- * Apart of that, the PIT has 4 registers: 0x40-0x42(data ports) and 0x43(command port)
