// Must include the appropriate microcontroller header file here
#include <reg52.h>

// Include oscillator / chip details here 
// (essential if generic delays / timeouts are used)
//  -
// Oscillator / resonator frequency (in Hz) e.g. (11059200UL)
#define OSC_FREQ (11059200UL)

// Number of oscillations per instruction (4, 6 or 12)
// 12 - Original 8051 / 8052 and numerous modern versions
//  6 - Various Infineon and Philips devices, etc.
//  4 - Dallas, etc.
//
// Take care with Dallas devices 
// - Timers default to *12* osc ticks unless CKCON is modified 
// - If using generic code on a Dallas device, use 12 here
