The IRAMSTBY pin provides keep-alive power to RAM when the main power supply is shut down. The
IRAMSTBY pin can be powered directly from a battery using an internal shunt regulator or via a small
battery for standby use. See
While power is off, the IRAMSTBY supply powers the following:

The internal memory map is organized as a single 4-Mbyte block. The user can assign this block to one of
eight locations by programming a register in the USIU (IMMR[ISB]). The eight possible locations are the
