Hello everyone,

 

I am new to the M52259 Coldfire and I have read the AN3854 Mini-FlexBus.pdf (Rev. 0, 04/2009) application note concerning this topic.

 

My question... am I able to switch mini-flexbus modes (non-multiplexed to multiplexed and back again) at any time during runtime?

 

The reason:  I wanted to control an asyncronous RAM (that has a 16 bit data bus) and a Flash NAND (that has an 8 bit data bus), but I wanted to have 16 bit data access to the RAM).

 

thanks,

juanee
