Note 0:
Note 1:
The interrupt request is output on one of the IRQx signals as 024 buffer type. If EPP or
ECP Mode is enabled, this output is pulsed low, then released to allow sharing of interrupts.
In this case, the buffer type is OD24. Refer to the configuration section for more
information.
nCS -This pin is the active low chip select; it must be low for all chip accesses. For 12 bit
addressing, SA0:SA11, this input should be tied to GND. For 16 bit address qualification,
