The N variable represents the 

prescaler

factor (1, 8, 64, 256, or 1024). 

PWM16bit_Init must be called before using other functions from PWM Library.

You need a CMO on the given MCU (that supports PWM-16bit). 

Before calling this routine you must set the output pin for the PWM (according
to the datasheet):

DDRB.B1 = 1; // set PORTB pin 1 as output for the PWM-16bit 

This code example is for ATmega168, for different MCU please consult
datasheet for the correct pinout of the PWM module or modules.

Initialize PWM-16bit module:

PWM16bit_Init( _PWM16_PHASE_CORRECT_MODE_8BIT,
_PWM16_PRESCALER_16bit_8, _PWM16_NON_INVERTED, 255, _TIMER1)
