4.2 SYSCFG Module

The following system level features of the chip are controlled by the SYSCFG peripheral:

  • Readable Device, Die, and Chip Revision ID
  • Control of Pin Multiplexing
  • Priority of bus accesses different bus masters in the system
  • Capture at power on reset the chip BOOT[15:0] pin values and make them available to software
  • Special case settings for peripherals:
    • Locking of PLL controller settings
    • Default burst sizes for EDMA3 TC0 and TC1
    • Selection of the source for the eCAP module input capture (including on chip sources)
    • Clock source selection for EMIFA and EMIFB
  • Selects the source of emulation suspend signal (from DSP) of peripherals supporting this function.

Since the SYSCFG peripheral controls global operation of the device, its registers are protected against erroneous accesses by several mechanisms:

  • Additionally, many registers are accessible only by a host (DSP) when it is operating in its privileged mode. (ex. from the kernel, but not from user space code).
