Reaction Module (REACM)

Works in conjunction with the eQADC and eTPU2 to increase system

performance by removing the CPU from the current control loop.

System Integration Unit (SIU)

Controls MCU reset configuration, pad configuration, external

interrupt, general purpose I/O (GPIO), internal peripheral

multiplexing, and the system reset operation.

Static random-access memory (SRAM)

Provides storage for program code, constants, and variables

System timers

Includes periodic interrupt timer with real-time interrupt; output

compare timer and system watchdog timer

System watchdog timer (SWT)

Provides protection from runaway code

Temperature sensor

Provides the temperature of the device as an analog value
