CHAPTER 2-3: High-Speed CR Trimming
120 FM4 Peripheral Manual, Doc. No. 002-04856 Rev. *E
Example: When PCLK = 40 MHz (25 ns), frequency division ratio = 1/8, and TIMER1 = 100,
Tmax = (100 × 25 ns) / 8 = 312.5 ns
Note:
− The base timer used for trimming is ch.0.
PCLK in Figure 4-3 is an APB1 bus clock.
At this time, select the master clock as the main oscillation for PCLK.
