Timer1 uses the internal clock with 1:1 prescaling. The microcontroller uses the internal LPRC as the clock source, then, what would be the clock frequency to TMR1? Show your work.

Answer 1

To calculate the clock frequency to TMR1, we need to determine the frequency of the internal LPRC (Low Power RC) clock source.

The clock frequency of the internal LPRC is typically specified in the microcontroller's datasheet. Let's assume the datasheet specifies it as 32 kHz.

Since Timer1 is using a 1:1 prescaler, the clock frequency to TMR1 will be the same as the internal clock frequency.

Therefore, the clock frequency to TMR1 will be 32 kHz.

Work:
- Given: Internal LPRC clock frequency = 32 kHz.
- Since Timer1 uses 1:1 prescaling, the clock frequency to TMR1 will be the same as the internal clock frequency.
- Therefore, the clock frequency to TMR1 is 32 kHz.
