TABLE 23-17: INTERNAL CLOCK TIMING EXAMPLES
Note 1:
2:
3:
Assumption: Oscillator Postscaler is divide by 1.
Instruction Execution Cycle Time: TCY = 1 / MIPS.
Instruction Execution Frequency: MIPS = (FOSC * PLLx)/4 [since there are 4 Q clocks per instruction
cycle].

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