Register Name:
Access Type:
Offset:
Reset Value:
This register indicates for each pin when a logic value change has been detected (rising or falling edge). This is valid
whether the PIO is selected for the pin or not and whether the pin is an input or an output.
The register is reset to zero following a read, and at reset.
1 = At least one input change has been detected on the corresponding pin since the register was last read.
0 = No input change has been detected on the corresponding pin since the register was last read.
16.9.18
Register Name:
Access Type:
Offset:
This register is used to enable PIO output drivers to be configured as open drain to support external drivers on the same
pin.
1 = Enables multi-drive option on the corresponding pin.
0 = No effect.
