TMR0_ReadTimer()

uint16_t TMR0_ReadTimer

(

void

)

@Summary Reads the 16 bits TMR0 register value.

@Description This function reads the 16 bits TMR0 register value and return it.

@Preconditions Initialize the TMR0 before calling this function.

@Param None

@Returns This function returns the 16 bits value of TMR0 register.

@Example Initialize TMR0 module

Start TMR0 TMR0_StartTimer();

Read the current value of TMR0 if(0 == TMR0_ReadTimer()) { Do something else...

Reload the TMR value TMR0_Reload(); }

TMR0_Reload()

void TMR0_Reload

(

void

)

@Summary Reload the 16 bits value to TMR0 register.

@Description This function reloads the 16 bit value to TMR0 register. This function must be called to write initial value into TMR0 register.

@Preconditions Initialize the TMR0 before calling this function.

@Param None

@Returns None

@Example while(1) { if(TMR0IF) { Do something else...

clear the TMR0 interrupt flag TMR0IF = 0;

Reload the initial value of TMR0 TMR0_Reload(); } }

@Summary Writes the 16 bits value to TMR0 register.

@Description This function writes the 16 bits value to TMR0 register. This function must be called after the initialization of TMR0.

@Preconditions Initialize the TMR0 before calling this function.

@Param timerVal - Value to write into TMR0 register.

@Returns None

@Example #define PERIOD 0x8000 #define ZERO 0x0000

while(1) { Read the TMR0 register if(ZERO == TMR0_ReadTimer()) { Do something else...

Write the TMR0 register TMR0_WriteTimer(PERIOD); }

Do something else... }
