To set up the interrupt mechanism for Timer1 on the Explorer 16 development board, the following registers and bits need to be configured:
1. Timer1 Control Register (T1CON): This register controls the operation and configuration of Timer1.
- Bits TMR1ON (bit 15) and TMR1CS (bit 0): Set TMR1ON bit to enable Timer1 and TMR1CS bit to select the clock source for Timer1 (internal or external).
2. Timer1 Interrupt Enable Register (T1IE): This register enables the Timer1 interrupt.
- Bit TMR1IE (bit 0): Set this bit to enable the Timer1 interrupt.
3. Timer1 Interrupt Flag Register (T1IF): This register indicates the occurrence of the Timer1 interrupt.
- Bit TMR1IF (bit 0): This bit is automatically set when the Timer1 interrupt occurs. It needs to be cleared by the software before re-enabling the interrupt.
4. Timer1 Period Register (PR1): This register sets the period for Timer1.
- Setting the desired value in this register determines the period of Timer1 interrupt generation.
These registers and bits can be accessed and configured using the appropriate operations in the microcontroller's programming language, such as reading, writing, setting, and clearing bits. The exact steps and syntax may vary depending on the specific microcontroller being used.
