Modular Input/Output Subsystem (MIOS14)
17.10.3 MPWMSM Description
The purpose of the MPWMSM is to create a variable pulse width output signal at a wide range of
frequencies, independently of other MIOS14 output signals. The MPWMSM includes its own counter, and
thus does not use the MIOS14 counter bus set. However the MPWMSM uses the prescaled clock bus that
originates in the MIOS14 counter prescaler submodule (MCPSM). The MPWMSM pulse width can vary
from 0% to 100%, with up to 16 bits of resolution. The finest output resolution is the MIOS14 CLOCK
period multiplied by two (for a MIOS14 CLOCK with f
resolution is 50 ns). With the full 16 bits of resolution and the MCPSM set to divide by two, the period of
the output signal can range from 3.276 ms to 6.71 s (assuming f
By reducing the amount of bits of resolution, the output signal period can be reduced. For example, the
period can be as fast as 204.8 µs (4882 Hz) with 12 bits of resolution, as fast as 12.8 µs (78.125 KHz) with
eight bits of resolution, and as fast as 3.2 µs (312.5 KHz) with six bits of resolution (still assuming a f
= 40 MHz and the MCPSM set to divide by two).
The MPWMSM is composed of:
