Peripheral features and how this peripheral works

The System Integration Module interacts with a variety of other on-chip resources and provides multiple services.

Features

• Manages low power mode entry and exit.
• Software reset on-chip peripherals.
• Controls inter-peripheral muxing and signal relationships.
• Control voltage regulators.
• Provides write protection for safety critical memory mapped registers.
• Contains the information of chip's JTAG ID.
• Supports short addressing control.
• Internal Peripheral Extend Control Interfaces

How this driver is designed to make this peripheral works.

The SIM interacts with a variety of other on-chip resources, based on the behaviour, this driver is divided in several function groups.

• Low Power Mode Control Related Interfaces
  The APIs in this function group can be used to enter/exit low power mode(including WAIT mode and STOP mode) and config low power mode operation mode.
• Reset Related Interfaces
  The APIs in this function group can be used to software reset device and other internal module.
• Peripheral Signal Muxing Control Interfaces
  The APIs in this function group can be used to set the mux of peripheral signal.
• Voltage Regulators Control Interfaces
  The APIs in this function group can be used to control the low power mode on-chip regulators, including large voltage regulator and small voltage regulator.
• Write Protection Interfaces
  The APIs in this function group can be used to set write protection of some peripherals' registers.
• JTAG ID Interfaces
  The APIs in this function group can be used to return JTAG ID.
• Short Addressing Control Related Interfaces
  The APIs in this function group can be used to set short address location upper bits.
• Software Control Interfaces
  The APIs in this function group can be used to set software control registers.
• Internal Peripheral Extend Control Interfaces
  The APIs in this function group can be used to set other peripherals' extended features.
