Hello,
Does the TMS320F28335 simulator have any issues with moving long int types from registers (i.e. ACC) to memory? I read in another post the 2812 simulator has problems with address range 0x3fffc2-0x3fffff. (http://e2e.ti.com/support/development_tools/code_composer_studio/f/81/p/3661/13193.aspx)
The reason I ask is that I having problem with the piece of code shown below, which is contained in a function. When I set "a" to be greater than 70000000, only the low word is changed in memory and therefore "a" doesn't get set to 70000000 (= .0x042C1D80)
That is if I set a to 0x043B63A9 (= 71001001), the code will set a to 0x043B1D80.
The memory location I examined starts at 0xDE50 (The data page point is set to #0x379, which gives an address of 889*64 words/page*16 = 56912 = 0xDE50.)
I am using compiler version 6.1.3.

if (a< 0)
