read CRC Value of DRAM/PRAM Firmware
\param
pDev - pointer to the device interface
\param
ram - P_RAM or D_RAM
\param
StartAddr - start address of sector
\param
StopAddr - stop address of the sector
\param
count - number of words to write
\param
pCrc - ptr to Crc value
\return
IFX_SUCCESS or IFX_ERROR
Remark :
following applies to calculate the PRAM stop address by given start address
and number of words to write:
- Pram addresses are even : 0x0, 0x2, ....., 0x2*n
- Every instruction is 48 bits : 1 instruction = 3 Words
- Every PRAM address points to 1 instruction : 0x2n -> Word1, Word2, Word3
a PRAM buffer looks as follows:
\code
addresses | Instructions
0x0 -> 0xXXXX, 0xXXXX, 0xXXXX
0x2 -> 0xXXXX, 0xXXXX, 0xXXXX
0x4 -> 0xXXXX, 0xXXXX, 0xXXXX
0x6 -> 0xXXXX, 0xXXXX, 0xXXXX
0x8 -> 0xXXXX, 0xXXXX, 0xXXXX
.
.
.
0x2n -> 0xXXXX, 0xXXXX, 0xXXXX
\endcode
so, if 9 Words are written at address 0x2, the stop address is 0x6 as example
