— Lowest-priority software interrupt: level LP
Nested interrupts: higher priority level interrupt request can interrupt lower priority interrupt subroutine
Two programmable fast interrupts that can be assigned to any interrupt source
Notification to system integration module (SIM) to restart clock out of wait and stop states
Ability to relocate interrupt vector table
The masking of interrupt priority level is managed by the 56800E core.

Peripheral Highlights
One Enhanced Flex Pulse Width Modulator (eFlexPWM) module
— Up to nine output channels
— 16-bit resolution for center aligned, edge aligned, and asymmetrical PWMs
— Each complementary pair can operate with its own PWM frequency based and deadtime values
–4 Time base
– Independent top and bottom deadtime insertion
— PWM outputs can operate as complimentary pairs or independent channels
— Independent control of both edges of each PWM output
— 6-channel NanoEdge high resolution PWM
– Fractional delay for enhanced resolution of the PWM period and edge placement
– Arbitrary eFlexPWM edge placement - PWM phase shifting
– NanoEdge implementation: 520 ps PWM frequency resolution
— 3 Channel PWM with full Input Capture features
– Three PWM Channels - PWMA, PWMB, and PWMX
– Enhanced input capture functionality
— Support for synchronization to external hardware or other PWM
— Double buffered PWM registers
– Integral reload rates from 1 to 16
– Half cycle reload capability
— Multiple output trigger events can be generated per PWM cycle via hardware
— Support for double switching PWM outputs
— Up to four fault inputs can be assigned to control multiple PWM outputs
– Programmable filters for fault inputs
— Independently programmable PWM output polarity
— Individual software control for each PWM output
— All outputs can be programmed to change simultaneously via a FORCE_OUT event
— PWMX pin can optionally output a third PWM signal from each submodule
— 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:
– Crossbar module outputs
– External ADC input, taking into account values set in ADC high and low limit registers
Two independent 12-bit analog-to-digital converters (ADCs)
— 2 x 8 channel external inputs
— Built-in x1, x2, x4 programmable gain pre-amplifier
