Chip Select Module
16.2.3 Byte Strobes (BS[3:0])
These signals are individually programmed through the byte-enable mode bit, CSCRn[BEM],
described in
These generated signals provide byte data select signals, which are decoded from the transfer size,
A1, and A0 signals in addition to the programmed port size and burstability of the memory
accessed, as shown below.
The below table also shows the interaction of the byte-enable/byte-write enables with related
signals.
