ADSP-SC58x PWM Register List
The Pulse-Width Modulator unit (PWM) includes multiple timers (providing period flexibility) and channels (pro-
viding mode, interrupt, and pulse shape flexibility), permitting a wide variety of PWM output options for motor
control and other applications. A set of registers governs PWM operations. For more information on PWM func-
tionality, see the PWM register descriptions.
