Error Correction Status Module (ECSM)
19.2.1 Module Memory Map
The ECSM memory map is shown in Table 19-1 (a graphical layout of the registers is shown in Table 19-2
to better see Reserved areas in the memory map). The address of each register is given as an offset to the
ECSM base address. Registers are listed in address order, identified by complete name and mnemonic, and
lists the type of accesses allowed.
