Description
Reserved
These bits are always read as 0. The write value
should always be 0.
SDI Interrupt Request
Indicates whether the SDI (SDHI) interrupt
request is generated.
0: SDI interrupt request is not generated
1: SDI interrupt request is generated
Note: On the models not having the SDHI, this bit
