The driver computes from the desired period which clock divider it should be using. This computation assumes that the link between the register value and the actual divider value is raising 2 to the power of the registry value. div = 1 << regvalue This is true only for the first 5 values out of 8. Next values are 64, 256 and, 1024. This affects only the user only if he requests a period > 0.04369s.
