Can I used the MCU that do not have the pin of "wr" and "rd"  control the TNT4882? Such as avr(ATmega16),arm(AT91Sam7S64).If can, how to connect?There,the I/O outputs of ARM is 3.3v,Can I used it control TNT4882?

I'm sorry, I have poor English, there are many grammatical errors, can you understand?

Hello,

Most MCUs don't actually have the "wr" or "rd" pin.  What you do is use DIO to set the correct states interfacing to the ASICs.  Please check the datasheets for the TNT4882 to see the waveforms that are necessary for correct communication.

I hope this helps,
