The V850ES/SA2 and V850ES/SA3 access the internal peripheral I/O and external memory in 8-bit, 16-bit, or 32-
• The bus size of the internal peripheral I/O is fixed to 16 bits.
• The bus size of the external memory is selectable from 8 bits or 16 bits (by using the BSC register).
The operation when each of the above is accessed is described below. All data is accessed starting from the lower
The V850ES/SA2 and V850ES/SA3 support only the little endian format.
