System control module, which contains registers for the following functions:
Static device configuration
Debug and observability
Status
Pad configuration
I/O configuration
eFuse logic
Analog function control
System boot decoding logic
Thirteen system Mailboxes for communication between MPU, DSP and IPU subsystems.
SpinLock module for hardware semaphore between the MPU, DSP, and IPU subsystems
Inter-processor Communication Register
Three Pulse Width Modulation Subsystems (PWMSS), each containing Enhanced High Resolution Pulse Width Modulator (eHRPWM), Enhanced Capture (eCAP), and Enhanced Quadrature Encoded Pulse (eQEP) modules.
Real-Time-Clock Subsystem (RTCSS), supporting four external wake-up inputs and one power enable output, all of which are 3.3- or 1.8-V multivoltage I/Os. Note: RTC is only available on the AM571x family of devices
Eight general-purpose input/output (GPIO) modules with up to 32 I/Os each. One GPIO module supporting wake-up request generation.
