isters in the device. The chip supports serial microcontroller interface and
two kinds of parallel microcontroller interface: Motorola multiplexed mode
and Intel multiplexed mode. Different microcontroller interfaces can be
selected by setting MODE[1:0] pins to different values. Refer to

MODE[1:0] pins are set to ‘10’, Parallel-Multiplexed-Motorola interface is
selected. When MODE[1:0] pins are set to ‘11’, Parallel-Multiplexed-Intel
Interface is selected.

mode, the registers are programmed through a 16-bit word which contains
an 8-bit address/command byte (5 address bits A0~A4 and bit R/W) and
an 8-bit data byte (D0~D7). When bit R/W is ‘1’, data is read out from pin
SDO. When bit R/W is ‘0’, data is written into SDI pin. Refer to Figure-19.
