I am using Kinetis K60 and i need to interface with a SRAM 512Kx16bit, it have 16bit of data and 20bit of address.
In order to optimize the pin usage I select CSCRn[BLS]=1
On “K61 Sub-Family Reference Manual, Rev. 2, Dec 2011” par 33.4.3 there are the suggested connection, but but this is different from that present in the document AN4393 “Using FlexBus Interface for Kinetis Microcontrollers, Rev. 0, 05/2012” al par. 2.3
Someone has already occurred which is the correct connection and what signals FB_BEn should be connected to BHE and BHL of the SRAM with CSCRn[BLS]=1 ?
