Introduction
SPC56XL60/54
A FlexPWM module implements the following features:
● 16 bits of resolution for center, edge aligned, and asymmetrical PWMs
● Maximum operating frequency as high as 120 MHz
– Clock source not modulated and independent from system clock (generated via
secondary FMPLL)
● Fine granularity control for enhanced resolution of the PWM period
● PWM outputs can operate as complementary pairs or independent channels
● Ability to accept signed numbers for PWM generation
● Independent control of both edges of each PWM output
● Synchronization to external hardware or other PWM supported
● Double buffered PWM registers
– Integral reload rates from 1 to 16
– Half cycle reload capability
● Multiple ADC trigger events can be generated per PWM cycle via hardware
● Fault inputs can be assigned to control multiple PWM outputs
● Programmable filters for fault inputs
● Independently programmable PWM output polarity
● Independent top and bottom deadtime insertion
● Each complementary pair can operate with its own PWM frequency and deadtime
values
● Individual software control for each PWM output
● All outputs can be forced to a value simultaneously
● PWMX pin can optionally output a third signal from each channel
● Channels not used for PWM generation can be used for buffered output compare
functions
● Channels not used for PWM generation can be used for input capture functions
● Enhanced dual edge capture functionality
● Option to supply the source for each complementary PWM signal pair from any of the
following:
– External digital pin
– Internal timer channel
– External ADC input, taking into account values set in ADC high- and low-limit
registers
● DMA support
