RAM Module
The TLE984xQX RAM module provides physical implementation of the memory module as well as needed
complementary features and interface towards the core.
The module provides proper access through a 32-bit AHB-Lite data interface multiplexed on M0 system bus for
code/data access.
The RAM module in TLE984xQX has a capacity of 4 Kbyte, organized with words of 32 bits.
The module support 1 bit Error correction and 2 bits error detection per 32-bit word (actually requiring 7 bits
parity per word). When an ECC error occurs, the corresponding status flag in the register EDCSTAT will be set.
A double bit error can be configured via the interrupt enable bit in register EDCCON to trigger an exception.

RAM Addressing
The RAM, as visible from the memory map, is mapped at the address range 18000000H - 18000FFF. The module
is mapped in the code area of the M0 map regions and can be used as program memory for code fetching as
well as data storing.
