very strange thing about UC3B internal pull ups for TWI
ok, i think on my PCB design, the capacitance is quite low. anyway, i can try to run it at 400KHz with this external 10K resistor first. Thanks.

very strange thing about UC3B internal pull ups for TWI
now i have put two external 10K pull-ups and the TWI bus works. But I still just want to use the internal Pull-ups...

well, now i really wish i have that external pull-ups, but still why???

is it possible to have bus contention for FLASH on UC3B?
i think so, there is this PRAS0...PRAS15 and PRBS0...PRBS15 registers for setting this.

TIOB pin can't be used as timing capture???
i don't know about this on UC3A, check it yourself.

how to sync a TC clked by PWM with a TC clked by PBA?
yes, but my UC3B is not engineering sample. So there shouldn't be error in TC, right?

how to sync a TC clked by PWM with a TC clked by PBA?
just measured the result, and it got a delay of one PBA clk between the low 16bit timer output waveform and high 16bit timer input PWM clk. I think this problem comes from the...

how to sync a TC clked by PWM with a TC clked by PBA?
it seems it could work if i use the BURST function to block the PBA clock of low 16bit time and then it could be in sync.

is it possible to have bus contention for FLASH on UC3B?
ok, but i'm wondering if FLASH slave can connects to other masters? And if so, then other than CPU instruction, which ones can it connects to?
