6.3 On-chip SRAM
6.4 Memory map
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.
On-chip SRAM may be used for code and/or data storage. The SRAM may be accessed
as 8 bit, 16 bit, and 32 bit. The LPC2194 provides 16 kB of SRAM.
The LPC2194 memory maps incorporate several distinct regions, as shown in
In addition, the CPU interrupt vectors may be re-mapped to allow them to reside in either
flash memory (the default) or on-chip SRAM. This is described in
control”.
