3.5.37 Device ID register
This device ID register is a read-only register and contains the part ID for each
LPC111x/LPC11Cxx part. This register is also read by the ISP/IAP commands
(Section 26.5.11
).
Remark: This register returns the part ID for parts of the LPC1100, LPC1100C, and
LPC1100L series only. Use ISP/IAP to obtain the part ID for the LPC1100XL series.
The part IDs for the various parts are shown in the following list. Some parts have two
valid part IDs.
