Bits
Description
0x02
RegPullUp
0x00
7:0
Enables the pull-up for each IO
0 : Pull-up is disabled
1 : Pull-up is enabled
0x03
RegPullDown
0x00
7:0
Enables the pull-down for each IO
0 : Pull-down is disabled
1 : Pull-down is enabled
0x04
Reserved
0xXX
7:0
Unused
0x05
RegInterruptMask
0xFF
7:0
Configures which [input-configured] IO will trigger an interrupt on NINT pin
0 : An event on this IO will trigger an interrupt
1 : An event on this IO will NOT trigger an interrupt
7:6
Edge sensitivity of I/O[7]
5:4
Edge sensitivity of I/O[6]
3:2
Edge sensitivity of I/O[5]
0x06
RegSenseHigh
0x00
1:0
Edge sensitivity of I/O[4]
00 : None
01 : Rising
10 : Falling
11 : Both
7:6
Edge sensitivity of I/O[3]
5:4
Edge sensitivity of I/O[2]
3:2
Edge sensitivity of I/O[1]
0x07
RegSenseLow
0x00
1:0
Edge sensitivity of I/O[0]
00 : None
01 : Rising
10 : Falling
11 : Both
0x08
RegInterruptSource
0x00
7:0
Interrupt source (from IOs set in RegInterruptMask)
0 : No interrupt has been triggered by this IO
1 : An interrupt has been triggered by this IO (an event as configured in relevant
RegSense register occured).
Writing '1' clears the bit in RegInterruptSource and in RegEventStatus
When all bits are cleared, NINT signal goes back high.
0x09
RegEventStatus
0x00
7:0
Event status of all IOs.
0 : No event has occured on this IO
1 : An event has occured on this IO (an edge as configured in relevant RegSense
register occured).
Writing '1' clears the bit in RegEventStatus and in RegInterruptSource if relevant.
If the edge sensitivity of the IO is changed, the bit(s) will be cleared automatically

and RegPLDTable4
