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.
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.
To calculate the clock frequency supplied to Timer1 (TMR1), we need to consider the prescaler value and the clock source frequency.
In this case, the prescaling ratio is 1:1, meaning no division is applied. Therefore, the clock frequency to TMR1 is equal to the frequency of the clock source, which is the internal Low-Power RC Oscillator (LPRC) in this scenario.
To find the clock frequency of the LPRC, we need to refer to the microcontroller's datasheet or specifications. Each microcontroller may have a different LPRC frequency, so let's assume it is 32 kHz as an example.
Therefore, the clock frequency to TMR1 would be 32 kHz.
To calculate the clock frequency for Timer1 using the internal low-power RC (LPRC) as the clock source, we need to know the frequency of the LPRC and the prescaling value.
1. Determine the frequency of the LPRC:
The frequency of the LPRC can vary depending on the specific microcontroller. You can usually find this information in the microcontroller's datasheet or technical documentation. Let's assume the frequency of the LPRC is 32 kHz.
2. Determine the prescaling value:
The prescaling value determines how many clock cycles of the microcontroller's clock source are required to increment the Timer1 count by 1. In this case, it is mentioned that the prescaling is set to 1:1, which means no prescaling is applied. This means that every clock cycle of the microcontroller's clock source increments the Timer1 count by 1.
3. Calculate the clock frequency to TMR1:
Since there is no prescaling (1:1) and the LPRC frequency is 32 kHz, the clock frequency to Timer1 (TMR1) is equal to the LPRC frequency. Therefore, the clock frequency to TMR1 would be 32 kHz.
Please note that the actual frequency might differ depending on the specific microcontroller and its configuration. It is always best to consult the microcontroller's datasheet for accurate information.
