The mask register contains 7 mask bits, which select
which of the seven ports P24–P30 are to be monitored
(Table 15). Set the appropriate mask bit to enable that
port for transition detect. Clear the mask bit if transitions
on that port are to be ignored. Transition detection
works regardless of whether the port being monitored is
set to input or output, but generally, it is not particularly
useful to enable transition detection for outputs.
To use transition detection, first set up the mask register
and configure port P31 as an output, as described
above. Then enable transition detection by setting the
M bit in the configuration register (Table 10). Whenever
the configuration register is written with the M bit set,
the MAX6956 updates an internal 7-bit snapshot regis-
ter, which holds the comparison copy of the logic states
of ports P24 through P30. The update action occurs
regardless of the previous state of the M bit, so that it is
not necessary to clear the M bit and then set it again to
update the snapshot register.
When the configuration register is written with the M bit
set, transition detection is enabled and remains
enabled until either the configuration register is written
