Note 1: Assumption: Oscillator Postscaler is divide by 1.
2: Instruction Execution Cycle Time: TCY = 1 / MIPS.
3: Instruction Execution Frequency: MIPS = (F
OSC * PLLx)/4 [since there are 4 Q clocks per instruction
cycle].

Note 1: Frequency calibrated at 7.372 MHz ±2%, 25°C and 5V. TUN <3:0> bits can be used to compensate for
temperature drift.
2: Overall FRC variation can be calculated by adding the absolute values of jitter, accuracy and drift percent-
ages.
