The primary oscillator is used as the clock source and its frequency is 7.648 GHz. The PLL is used. In that case, what is Fcy (Internal instruction cycle frequency)? Also, what is Tcy? You must show your calculation. Failing to do so will result zero mark for this question.
Fosc (Processor/Peripheral clock Frequency) = 7.648 x 4 = 30.592/2 = 15.296 GHz.
Tcy (Instruction Cycle) = 1/15.296 = 0.065uSec.
How to calculate Fcy?
Fosc (Processor/Peripheral clock Frequency) = 7.648 x 4 = 30.592/2 = 15.296 GHz.
Tcy (Instruction Cycle) = 1/15.296 = 0.065uSec.

Fcy is calculated by dividing Fosc by a factor known as the instruction cycle divider (IDIV). The IDIV value is determined by the specific microcontroller being used.
To calculate Fcy, we need to know the value of IDIV.
Fcy = Fosc / IDIV
Since the information provided does not specify the value of IDIV, it is not possible to calculate Fcy without this additional information.
