Stand-By RAM (SBRAM)

The SBRAM provides 1 Kbyte of memory supplied by the wake-up power domain

(DMP_M). Its main purpose is to retain state while the system power domain (DMP_1)

is switched off.

Unlike the other memories the SBRAM is not mapped into the address range of the

processor. Reading and writing is done via two address and two data SFRs. Details of

the access mechanism are described in Section 3.11.

Note: Code cannot be executed out of the SBRAM.

Marker Memory (MKMEM)

The MKMEM provides 4 bytes of memory supplied by the wake-up power domain. Its

purpose is the same as the SBRAM.

The MKEM consists of 2 16-bit SFRs that are accessible as all other SFRs. Details are

described in Section 3.11.

Note: It goes without saying that code cannot be executed out of the MKMEM.
