Single Register Write Cycle
The single register write cycle is shown in
gle register write is accomplished by asserting a valid
address (MPA), asserting the chip enable (MPCE = LOW)
and de-asserting the output enable (MPOE = HIGH) during
the first clock cycle (Cycle 0). These signals should hold
these values at least until the rising edge of the third clock
cycle (Cycle 2).

The write enable signal should be asserted (MPWE = LOW)
during the second clock cycle (Cycle 1). Data (MPD) to be
written to the specified address should be asserted during
the same clock cycle that the write enable is asserted
(Cycle 1). The register write cycle is then completed by
de-asserting the write enable during the third clock cycle
(Cycle 2).
