Here is an example of a TMR1Init() function that configures the necessary registers for TMR1 to generate interrupts at a 200 usec interval, using the TCY clock source with a prescaler value of 1:8:
```c
#include <xc.h> // Include the necessary header file for your microcontroller
void TMR1Init() {
T1CONbits.TON = 0; // Disable Timer1
T1CONbits.TCS = 0; // Select Internal Clock (FOSC/4)
T1CONbits.TCKPS = 0b11; // Set prescaler value to 1:8
TMR1 = 0x00; // Clear Timer1 register
PR1 = 400; // Set period register to achieve 200 usec interval
IPC0bits.T1IP = 5; // Set Timer1 interrupt priority to 5
IFS0bits.T1IF = 0; // Clear Timer1 interrupt flag
IEC0bits.T1IE = 1; // Enable Timer1 interrupt
T1CONbits.TON = 1; // Enable Timer1
}
```
Make sure to include the correct header file for your microcontroller and update any register names accordingly. Also, adjust the PR1 value to achieve the desired interval based on your clock frequency.
you are using timr1 of the explorer 16 board. we are going to tuse TMR1 to generate interrupt (with pirority 5) at 200 usec interval. we will be using TCY as the clock source for TMR1 with a prescaler value of 1:8. write an TMR1Init() to configure all the related registers for TMR1.
