1)I did the parallel port programming for ADSP 21364 ,but i did not initialize PLL in that still i could find my code working as i had set the PPBUR3 =55.5Mbytes/sec ,how did this happen.my PCLK is not 166 as PLL is not initialized.
2)Does visual DSP support unsigned short int,& unsigned char & other similar datatypes.
3)I wrote a simple program on visual DSP,it was a simple calculation program no peripherals included when i compiled during linking i gotcould not locate DM range 0x1200000 -0x1203ffE (seg_sram) on target ,what can be the reason?
4)For parallel port 16-bit mode, the address rangeis 0x0 to 0xFFFF which is a 128K bytes (32K 32-bit words)how it comes to 128 K it should be 65536 bytes.
C:\Program Files\Analog Devices\VisualDSP 5.0 (3)\213xx\Examples\ADSP-21364 EZ-KIT Lite
4. For 16 bits the address range is 0x0 to 0xffff => 65536* 16 bits =>131072 bytes = 128k bytes
