Modular Input/Output Subsystem (MIOS14)
17.10 MIOS14 Pulse Width Modulation Submodule (MPWMSM)
The MIOS14 pulse width modulation submodule (MPWMSM) is a function included in the MIOS14
library. It allows pulse width modulated signals to be generated over a wide range of frequencies,
independently of other MIOS14 output signals and with no software intervention. The output pulse width
can vary from 0% to 100%. The minimum pulse width is twice the minimum MIOS14 CLOCK period
(i.e., the minimum pulse width is 50 ns when f
double-buffered mode, to avoid spurious update.
The following sections describe the MPWMSM in detail. A block diagram of the MPWMSM is shown in
