I have a problem with FMSC. I want to use FSMC single synchronous burst transfer with PSRAM. The memory has a 16bit data width and i read into ref. manual that "When the selected bank is configured in synchronous burst mode, if an AHB single-burst
transaction is requested, the FSMC performs a burst transaction of length 1 (if the AHB
transfer is 16-bit), or length 2 (if the AHB transfer is 32-bit) and de-assert the chip select
signal when the last data is strobed.".

Can I choose the AHB size or it is fixed to 32bit?
