INT_STAT_0 (GPIO) Register Description

Register NameINT_STAT_0
Relative Address0x0000000218
Absolute Address 0x00FF0A0218 (GPIO)
Width32
TypemixedMixed types. See bit-field details.
Reset Value0x00000000
DescriptionInterrupt Status (GPIO Bank0, MIO)

This registers shows if an interrupt event has occurred or not. Writing a 1 to a bit in this register clears the interrupt status for that bit. Writing a 0 to a bit in this register is ignored. This register controls bank0, which corresponds to MIO[25:0].
