MSI frequency range

Type: int

Help

Frequency range of MSI when MSI range is provided in RCC_CR register Range 0: 100kHz Range 1: 200kHz Range 2 around 400 kHz Range 3 around 800 kHz Range 4: 1 MHz Range 5: 2 MHz Range 6: 4 MHz (reset value) Range 7: 8 MHz Range 8: 16 MHz Range 9: 24 MHz Range 10: 32 MHz Range 11: 48 MHz
