EVAL-ADUCM420QSP1Z
Keil SRAM Mode
Several .sct and .s files from the example program allow users to
select the desired SRAM: M420_SramModeX.sct and
SetSramModeX.s. The X in the file name specifies the mode
number (0 to 3) for the SRAM.
1. After the example program is opened from the Keil IDE, the
files located in the same folder are shown. Ensure that the
.sct and .s files from the example folder (see Figure 34) are
used with the corresponding SRAM mode being tested.

2. By default, the M420_SramMode macro uses SRAM
Mode 0. The SetSramMode0.s assembly file is added to
the subdirectory as shown in Figure 35. Specify which
SRAM mode to test in the main.c file. By default, SRAM
Mode 0 is tested (see Figure 36).

3. After following Step 1 and Step 2, proceed to set up the .sct
file located in Flash > Configure Flash Tools > Linker. Refer
to Figure 37 to check the settings highlighted in green are
correct and that the correct scatter file is chosen (based on
the SRAM mode configuration).
4. Running the settings in Figure 38 shows that the ISRAM is
placed in debug mode via the Disassembly window.
