are disabled. However, the ISP Flash Erase command can be executed at any time

(no matter whether the CRP is on or off). Removal of CRP is achieved by erasure of

full on-chip user Flash. With the CRP off, full access to the chip via the JTAG and/or

ISP is restored.

6.3 On-Chip static RAM

On-Chip static RAM may be used for code and/or data storage. The SRAM may be

accessed as 8-bits, 16-bits, and 32-bits. The LPC2114/LPC2124 provide 16 kB of

static RAM.

6.4 Memory map

The LPC2114/LPC2124 memory maps incorporate several distinct regions, as shown

in the following ﬁgures.

In addition, the CPU interrupt vectors may be re-mapped to allow them to reside in

either Flash memory (the default) or on-chip static RAM. This is described in Section

6.19 “System control”.
