Type Reset Description
R/W 0h
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
R/W 0h 0: No interrupt generation
1: Enable interrupt generation for this IO (Only effective if
EDGE_DET is enabled)
R/W 0h
Enable generation of edge detection events on this IO
0h = NONE : No edge detection
1h = Negative edge detection
2h = Positive edge detection
3h = Positive and negative edge detection
R 0h
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
R/W 3h
Pull control
1h = DWN : Pull down
2h = UP : Pull up
3h = DIS : No pull
R/W 0h 0: Normal slew rate
1: Enables reduced slew rate in output driver.
R/W 0h
Selects IO current in combination with IOSTR
0h = 2MA : 2 mA
1h = 4MA : 4 mA
2h = 4_8MA : 4 or 8 mA
8 mA if IO is double drive strength
R/W 0h
Select drive strength IO
0h = Automatic drive strength (2, 4, 8 mA @ VDDS)
1h = Minimum drive strength (2, 4, 8 mA @ 3.3 V)
2h = MED : Medium drive strength (2, 4, 8 mA @ 2.5 V)
3h = Maximum drive strength (2, 4, 8 mA @ 1.8 V)
R 0h
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
