To calculate the instruction cycle frequency (Fcy), we need to determine the frequency after the PLL is applied.
The Explorer 16 development board uses a PLL (Phase-Locked Loop) to multiply the primary oscillator frequency by a certain factor. The PLL can multiply the frequency by either 4x, 8x, or 16x, depending on the settings.
Assuming the PLL is set to multiply the frequency by 16x, the formula to calculate the instruction cycle frequency (Fcy) is:
Fcy = Primary Oscillator Frequency * PLL Multiplier / 4
Fcy = 14.535 MHz * 16 / 4
Fcy = 58.14 MHz
Therefore, the instruction cycle frequency (Fcy) is 58.14 MHz.
The primary oscillator frequency on explorer 16 is 14.535 MHZ. PLL is used. What is the instruction cycle frequency (Fcy)?
