Description
Reserved
These bits are always read as 0. The write value should
always be 0.
ADI Interrupt Request
Indicates whether an ADI (ADC) interrupt request is
generated.
0: An ADI interrupt request is not generated
1: An ADI interrupt request is generated
TXI2 Interrupt Request
Indicates whether a TXI2 (SCIF) interrupt request is
generated.
0: TXI2 interrupt request is not generated
1: A TXI2 interrupt request is generated
BRI2 Interrupt Request
Indicates whether a BRI2 (SCIF) interrupt request is
generated.
0: A BRI2 interrupt request is not generated
1: A BRI2 interrupt request is generated
RXI2 Interrupt Request
Indicates whether an RXI2 (SCIF) interrupt request is
generated.
0: An RXI2 interrupt request is not generated
1: An RXI2 interrupt request is generated
ERI2 Interrupt Request
Indicates whether an ERI2 (SCIF) interrupt request is
generated.
0: An ERI2 interrupt request is not generated
1: An ERI2 interrupt request is generated
