Parallel Port Operation
When using the parallel interface on the DS26334 the user has the option for either multiplexed bus operation or
nonmultiplexed bus operation. The ALE pin is pulled high in nonmultiplexed bus operation. The DS26334 can
operate with either Intel or Motorola bus-timing configurations selected by MOTEL pin. This pin being high selects
the Intel mode. The parallel port is only operational if MODESEL pin is pulled high. The following Table lists all the
pins and their functions in the parallel port mode. See the timing diagrams in Section 9 for more details.

5.1.3
Interrupt Handling
There are four sets of events that can potentially trigger an Interrupt. The interrupt functions as follows:
When status changes on an interruptible event, INTB pin will go low if the event is enabled through the
corresponding Interrupt Enable Register. The INTB has to be pulled high externally with a 10k
resister for
wired-OR operation. If a wired-OR operation is not required, the INTB pin can be configured to be high when
not active by setting register GISC.INTM
When an Interrupt occurs the Host Processor has to read the Interrupt Status register to determine the source
of the Interrupt. The read will also clear the Interrupt Status register and this will clear the output INTB pin. The
Interrupt Status register can also be configured as clear on write as per register
.
GISC.CWE
Subsequently the host processor can read the corresponding Status Register to check the real-time status of
the event.
. When set to clear
on write, and interrupt status register bit (and the interrupt it generates) will only be cleared on writing a ‘1’ to
it’s bit location in the interrupt status register. This makes is possible to clear interrupts on some bits in a
register without clearing them on all bits.
