Negative Mask Register Port 0/2
The Negative Mask Register for Port 0/2 (base + 1A
written. This register enables the Negative Edge Detect Register to
capture high to low transitions on individual channels. When a bit is
set to "1" in this register it enables that channel to be captured in the
corresponding bit in the Negative Edge Detect Register. When a bit is
set to "0" it is disabled. If bit 4 of the Control/Status Register is low
("0"), Port 0 data is accessed. If bit 4 is high ("1"), Port 2 data will be
accessed.

The Debounce Clock Register (base + 1E
This register controls the clock rate to the debouncers. There are only
two programmable counters for all four ports. Port 0 and Port 1 share
one counter. This counter is controlled when bit 4 of the
Control/Status Register is "0". Port 2 and Port 3 share the other
counter and are accessed when bit 4 of the Control/Status Register is
N
"1". A 2 counter is used to generate the clock, so times are binary
powers. Table 3-1 shows the allowed values for this register. This
register is mirrored at address base + 2E
1E is equivalent to base + 2E

When BS = 0 in the Status/Control Register, the debounce clock for
Port 0 and Port 1 are accessed. Port 0 and Port 1 use the same
debounce clock. With BS = 0 any value programmed into or read from
this register will be the same as the register at b + 2E
