i want to use pwm in my project. I am using pic16f18875 controller and xc8 compiler.
i have configured the pwm and i was configuring timer 2 for that. But i am not getting the pwm output.
I am trying to understand the use of register TxRST in timer.I want to understand the use of TxRST register. currently i have set the register value as 0xFF.
here is my code for pwm and timer register

Code:
void PWM1_Initialize(void)

// MODE PWM; EN enabled; CCP1FMT right_aligned;
CCP1CON = 0x8F;
// RH 0;

// RL 0;
CCPR1L = 0x00;
// Selecting Timer 2
CCPTMRS0bits.C1TSEL = 0x1;
CCP1PPS = 0x12;
}
void PWM1_LoadDutyValue(uint16_t dutyValue)
{
dutyValue &= 0x03FF;
// Load duty cycle value
if(CCP1CONbits.CCP1FMT)
{
dutyValue <<= 6;
CCPR1H = dutyValue >> 8;
CCPR1L = dutyValue;
}
else
{
CCPR1H = dutyValue >> 8;
CCPR1L = dutyValue;
}
}
uint8_t PWM1_OutputStatusGet(void)
{
// Returns the output status
return(CCP1CONbits.OUT);
}
void initTimer2(void)
{
T2CLKCON = 0x01;
T2CON = 0x80;
T2HLT = 0x00;
T2RST = 0xFF;
}
