When active low, the device needs servicing. It remains active until
When MSyncMode is asserted high, this pin is an address strobe
pin. When the MAS* pin is asserted low, it indicates a valid
address, MicroAddr[11:0]. This signal is used to qualify read and
write accesses.
When MSyncMode is asserted low, this pin is a write control pin.
When MWr* is asserted low, a write access is enabled and the
MicroData[7:0] pin values will be written to the memory location
indicated by the MicroAddr[11:0] pins. The write access assumes
the device is chip selected (MCS* = 0), a read access is not being
requested (MRd* = 1), and the device is not being reset (Reset* =
1).

A bi-directional data bus for reading and writing data to internal
registers.
the pending interrupt is processed by the Interrupt Service
Routine. This pin is an open drain output for an external wired OR
logic implementation. An external pull-up resistor is required for
this pin.
