CPU Interface Bus Width Selection
Combination of CPU Interface Input Pins
: Don’t care
The bus width is selected by the *HWR/*BYTE pin level at the rising of the *RST pin.
The 8-bit width is selected when *HWR/*BYTE pin is “L” level and 16-bit when it is “H” level.
With the 8-bit width selected, fix the *HWR/*BYTE pin to “L”.
