Bits[31:1] of the alias word have no effect on the bit-band bit. Writing 0x01 has the same effect as writing
0xFF
. Writing 0x00 has the same effect as writing 0x0E.
Reading a word in the alias region:
0x00000000 indicates that the targeted bit in the bit-band region is set to zero
0x00000001 indicates that the targeted bit in the bit-band region is set to 1
2.2.5.2 Directly accessing a bit-band region
Section 2.2.3 (p. 16) describes the behavior of direct byte, halfword, or word accesses to the bit-
band regions.
2.2.6 Memory endianness
The processor views memory as a linear collection of bytes numbered in ascending order from
zero. For example, bytes 0-3 hold the first stored word, and bytes 4-7 hold the second stored word.
Section 2.2.6.1 (p. 20) describes how words of data are stored in memory.
2.2.6.1 Little-endian format
The EFM32 uses a little-endian format, in which the processor stores the least significant byte of a word
at the lowest-numbered byte, and the most significant byte at the highest-numbered byte. For example:
Mem ory
Regist er
Address A
A+ 1
lsbyt e
m sbyt e
A+ 2
A+ 3

2.2.7 Synchronization primitives
The Cortex-M3 instruction set includes pairs of synchronization primitives. These provide a non-blocking
mechanism that a thread or process can use to obtain exclusive access to a memory location. Software
can use them to perform a guaranteed read-modify-write memory update sequence, or for a semaphore
mechanism.
A pair of synchronization primitives comprises:
A Load-Exclusive instruction
Used to read the value of a memory location, requesting exclusive
access to that location.
A Store-Exclusive instruction
Used to attempt to write to the same memory location, returning a
status bit to a register. If this bit is:
0
it indicates that the thread or process gained exclusive access to
the memory, and the write succeeds,
1
it indicates that the thread or process did not gain exclusive
access to the memory, and no write is performed,
The pairs of Load-Exclusive and Store-Exclusive instructions are:
