***DataSheet***
Note that EM_BA[1:0] are used as low-order address lines for the asynchronous interface. For example, in
Figure 4-5 and Figure 4-6, the flash memory is not byte-addressable and its A[0] input selects a 16-bit
value. The corresponding DSP address comes from EM_BA[1]. The remaining address lines from the
DSP (EM_A[12:0]) drive a word address into the flash inputs A[13:1].
***EMIF USER GUIDE***
The EMIF address pins EM_A[x:0] always provide the least significant bits of a 32-bit word address. The BA[1:0] pins
either provide the half-word and byte selection or provide EM_A[23:22] functionality, according to the data
bus width configured in the Asynchronous 1 Configuration Register (A1CR).
