mode is used for active-low, wired-OR hook-ups
with multiple peripherals connected to the micro-
controller interrupt input pin.
Many conditions can cause an interrupt, as listed in
the interrupt status register descriptions. Each
source may be masked off using mask register

Note 1: AD2 is derived from a resistor attached to the EMPH pin,
Note 2: If operation is a write, this byte contains the Memory Address Pointer, MAP
Note 3: If operation is a read, the last bit of the read should be a NACK(high)

bits. In addition, each source may be set to rising
edge, falling edge, or level-sensitive. Combined
with the option of level-sensitive or edge-sensitive
modes within the microcontroller, many different
set-ups are possible depending on the needs of
the equipment designer.
