Description
PARTNUM
[15:0]
MCU Part Number
Device part number of the MCU.
0101_0110_0100_0101: Device with 2 MB flash memory
For the full part number this field needs to be combined with MIDR2.PARTNUM[0:7]

PKG[4:0]
Package Settings
Can be read by software to determine the package type that is used for the particular device:
0b10001: 176-pin QFP
0b10101: 208-pin QFP
0b10100: 416-pin BGA
MAJOR_MASK[3:0] Major Mask Revision
Counter starting at 0x0. Incremented each time when there is a resynthesis.
MINOR_MASK[3:0] Minor Mask Revision
Counter starting at 0x0. Incremented each time a mask change is done.
