Modular Input/Output Subsystem (MIOS14)
where:
A few examples of frequencies and resolutions that can be obtained are shown in
When using 16 bits of resolution on the comparator (MODE[2:0] = 0b000), the output can vary from a 0%
duty cycle up to a duty cycle of 65535/65536. In this case it is not possible to have a 100% duty cycle. In
cases where 16-bit resolution is not needed, it is possible to have a duty cycle ranging from 0% to 100%.
Setting bit 15 of the value stored in register B to one results in the output being ‘always set’. Clearing bit
15 (to zero) allows normal comparisons to occur and the normal output waveform is obtained. Changes to
and from the 100% duty cycle are done synchronously on an A or B match, as are all other width changes.
