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)
–
McASP AMUTEIN selection and clearing of AMUTE status for the three McASP peripherals
–
Control of the reference clock source and other side-band signals for both of the integrated USB
PHYs
–
Clock source selection for EMIFA and EMIFB
•
Selects the source of emulation suspend signal (from either ARM or DSP) of peripherals supporting
this function.
•
Control of on-chip inter-processor interrupts for signaling between ARM and DSP
Many registers are accessible only by a host (ARM or DSP) when it is operating in its privileged mode.
(ex. from the kernel, but not from user space code).
