Note:
1
The oscillator generates a stable clock 1.5 ms after the power supply becomes stable.
2
The Pll lock time is given by the following formula:
Lock time = 4 ms / (decimal equivalent of PLL charge pump bit setting + 1)
The PLL charge pump (CP) bits are in the PLL1/2_CTR register in the Miscellaneous
register block. Please refer to the user manual for more details.
For example, if the application software sets CP = 01110 = 14 (decimal), then:
Lock time = 4 ms / 15 = 267 μs.
