JTAG ports setup in AT91SAM9260

Thu Jan 11, 2007 11:08 pm

I can not find programmer's manual for AT91SAM9260.
I have two questions:
1. I have a C program for 8051 chip (x86 platform), which set up JTAG ports using first parallel interface, with the base port = 0x378, status port = 0x379 and control port = 0x37A.
What are the JTAG ports in AT91SAM9260?
I can only find the memory bit address for them in the AT91SAM9260 manual:
TCK, TMS, TDI and TDO, they are in the range from 0xFFFF F600 to oxFFFF F800 using PIOB.

2. In ARM, the port type is unsigned int. Can I use unsigned short?

Best Regards
