This interrupt sets the interrupt detection sensitivity of each interrupt pin (level or
edge mode).
This interrupt sets the interrupt detection sensitivity of each interrupt pin (active
high/low or rising/falling edge depending on sensitivity mode).
When enabled, both-edge mode causes interrupts to be generated on both rising
and falling edges.

Table 8-35 GPIO 7-0 Interrupt Active High/Low Register (0x675)
Bit
R/W
Description
Default
7:0
R/W
GPIO7:GPIO0
1 = Active high / rising edge
0 = Active low / falling edge
Note: Function depends on whether the bit is in level or
edge mode.

Bit
R/W
Description
Default
7:0
R/W
GPIO7:GPIO0
1 = Both-edge mode enabled
0 = Both-edge mode disabled
Note: The GPIO bit must be in edge mode for both-edge
mode to work.
