20.5.3.7
Interrupt Filter Enable Register (IFER)
This register is used to enable a digital filter counter on the corresponding interrupt pads to filter out
glitches on the inputs.
20.5.3.8
Pad Configuration Registers (PCR0–PCR148)
The Pad Configuration Registers allow configuration of the static electrical and functional characteristics
associated with I/O pads. Each PCR controls the characteristics of a single pad.
Please note that input and output peripheral muxing are separate.
•
For output pads:
— Select the appropriate alternate function in Pad Config Register (PCR)
— OBE is not required for functions other than GPIO
•
For input pads:
— Select the feature location from PSMI register
— Set the IBE bit in the appropriate PCR
•
For normal GPIO (not alternate function):
— Configure PCR
— Read from GPDI or write to GPDO
Offset:0x0030
Access: User read/write
