Functional Description and Application Information
4.26.4
The part ID is located in two 8-bit registers PARTIDH and PARTIDL (addresses 0x001A and 0x001B). The read-only value is a
unique part ID for each revision of the chip.
4.26.5
The clock and reset generator module (CRG) provides the internal clock signals for the core and all peripheral modules.
shows the clock connections from the CRG to all modules.
Consult the CRG specification for details on clock generation.
