Honored Contributor --- Quote Start --- hello vizzie, i just realized that rs232 cant handle 31 bits. mem_write is 32 bits width. that means what comes out of my address decoder is also 32 bits width. tx_data_in must not be more than 8 bits..do you have any idea on this? --- Quote End --- I suppose you mean you have 32 bits data bus from the processor and the device data width is only 8-bits (right?). If there are no specific bus-arbitration rules in zpu (which appears to be true), then what abt connecting the least significant 8-bits of data-bus to tx_data_in?
