Chapter 21: LPC13xx Flash memory programming firmware
21.11 Sector numbers
Some IAP and ISP commands operate on sectors and specify sector numbers. The
following table shows the correspondence between sector numbers and memory
addresses for LPC13xx devices.
21.12 Code Read Protection (CRP)
Code Read Protection is a mechanism that allows the user to enable different levels of
security in the system so that access to the on-chip flash and use of the ISP can be
restricted. When needed, CRP is invoked by programming a specific pattern in flash
location at 0x0000 02FC. IAP commands are not affected by the code read protection.
Important: any CRP change becomes effective only after the device has gone
through a power cycle.
