Change	Topics affected
Abbreviated RealView ICE to RVI. Also, mentioned DSTREAM when mentioning RVI.	angel_SWIreason_EnterSVC (0x17) SYS_CLOCK (0x10) SYS_ELAPSED (0x30) SYS_HEAPINFO (0x16) SYS_TICKFREQ (0x31) SYS_TIME (0x11).

Table 23. Differences between issue A and issue B

Change	Topics affected
Added note that the overall layout of the memory maps of devices based around the ARMv6-M and ARMv7-M architectures are fixed.	Tailoring the image memory map to your target hardware
Added links to Scatter-loading file with link to bit-band objects, ARMARMv7-M, and ARMARMv6-M.	Tailoring the image memory map to your target hardware
Added links to Scatter-loading file with link to bit-band objects.	Scatter-loading description file
Added a new topic called Scatter-loading file with link to bit-band objects.	Scatter-loading file with link to bit-band objects
For `SYS_ELAPSED`, clarified that R0 contains 0 on success and -1 on failure.	SYS_ELAPSED (0x30)
Clarified that the linker uses a version of the library setup code rather than the `__user_initial_stackheap()` function when tailoring the stack and heap placement in the scatter-loading file.	Reset and initialization
