Writing Data using WE_BE Latch

[sanders]

Hi,

I am using the MK60DN512 to communicate with some comms ICs on the same board. I use an 8-bit multiplexed bus and was hoping to use WE_BE signal to latch data into these peripherals during write operations. However, I cannot seem to do this. I suspect my understanding is not complete re. use of WE_BE. I was using FB_BE_31_24 as the latch to transfer 8 and 16 bit values (byte lane shift enabled).

I wondert if you could shed light on this?

Hi

Please check the K60 reference manual, the byte select pin is /FB_BE_31_24 for 8-bit port size, whatever CSCRn[BLS] bit:

There is an application note AN4393 about FlexBus application.

Wish it helps.

Have a great day,
Ma Hui
