History of updates to CMSISv2p00_LPC11Uxx
|
||||
=========================================
|
||||
|
||||
2 June 2011
|
||||
-----------
|
||||
Updated version of core_cm0.h from ARM (V2.03, dated
|
||||
23. May 2011) - with main change being removal of
|
||||
core debug registers (which are not accessible from
|
||||
application code on Cortex-M0).
|
||||
|
||||
8 April 2011
|
||||
------------
|
||||
Minor fix to LPC11Uxx.h to change LPC_CT32B1_BASE from
|
||||
0x40014000 to 0x40018000
|
||||
|
||||
23 March 2011

LPC11Uxx CMSIS 2.0 library project using ARM
|
||||
Cortex-M0 CMSIS files as supplied in ARM's CMSIS 2.0
|
||||
December 2010 release, together with device/board
|
||||
specific files from NXP.
