25. Chip Identifier (CHIPID)

Description
Chip Identifier registers permit recognition of the device and its revision. These registers provide
the sizes and types of the on-chip memories, as well as the set of embedded peripherals.
Two chip identifier registers are embedded: CHIPID_CIDR (Chip ID Register) and CHIPID_EXID
(Extension ID). Both registers contain a hard-wired value that is read-only. The first register con-
tains the following fields:
The second register is device-dependent and reads 0 if the bit EXT is 0.
Table 25-1.
• EXT - shows the use of the extension identifier register
• NVPTYP and NVPSIZ - identifies the type of embedded non-volatile memory and its size
• ARCH - identifies the set of embedded peripherals
• SRAMSIZ - indicates the size of the embedded SRAM
• EPROC - indicates the embedded ARM processor
• VERSION - gives the revision of the silicon
