Part ID Assignments

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. Table 213 shows the assigned part ID number and Mask Set number.

System Clock Description

The clock and reset generator module (CRG) provides the internal clock signals for the core and all peripheral modules. Figure 45

shows the clock connections from the CRG to all modules.

Consult the CRG specification for details on clock generation.
