is it possible to have bus contention for FLASH on UC3B?
yes, i understand this FLASHC speed limit, but I'm wondering if there is any possible bus conflict, that will make this flashc access even slower?

delay_x.h transplant on AVR32 UC3B
ok, just done the fix. I tested it a little bit and it's delay is correct now for F_CPU > 33000000Hz. I assume that if F_CPU is faster than 33MHz, then brne would take 4 clks...

UC3B design JTAGmkII communication stability problem!
i just have 10K pull-up for TCK pin. The TDI,TDO and TMS pins have no external pull-up or pull-down on my PCB, I use them as GPIO outputs to the level translator.

delay_x.h transplant on AVR32 UC3B
I just found out that this delay_x.h function is not accurate if AVR32 is running faster than 30MHz. This is because the extra delay for FLASHC. I will try to find the fix.

UC3B design JTAGmkII communication stability problem!
I connected TDI, TDO and TMS pins to bidirectional level translator txb0108, which is enabled by PA30 pin on my design. If I connect my JTAG adaptor to ths PCB, then PA30 would...
