Chapter 3: LPC43xx/LPC43Sxx Memory mapping
[1]
Top 8 kB at of memory starting at location 0x1008 8000 remain powered on in Sleep, Deep-sleep, and Power-down modes (see
[2]
To configure SRAM memory use for AHB or ETB, see
3.3.2 Bit banding
Bit-banding offers efficient bit accesses. Bits in the bit-band region (0x2000 0000 to
0x2010 0000 and 0x4000 0000 to 0x4010 0000) can be accessed in the so-called alias
region at 0x2200 0000 and 0x4200 0000. Reads return the respective bit from the
bit-band region. Writes perform an atomic read-modify-write on the respective bit of the
bit-band region. For details, see the
ARM Cortex-M4 technical reference manual
.
Remark:
Bit banding can not be used with the MAC_RWAKE_FRFLT register (see
