SDIN Wake Enable Flags — R/W. These bits control which SDI signal(s) may generate a wake
event. A 1b in the bit mask indicates that the associated SDIN signal is enabled to generate a wake.
Bit 0 is used for SDI[0]
Bit 1 is used for SDI[1]
Bit 2 is used for SDI[2]
NOTE: These bits are in the resume well and only cleared on a power on reset. Software must not
Reserved.
SDIN State Change Status Flags — R/WC. Flag bits that indicate which SDI signal(s) received a
state change event. The bits are cleared by writing 1s to them.
Bit 0 = SDI[0]
Bit 1 = SDI[1]
Bit 2 = SDI[2]

Reserved.
Flush Status — R/WC. This bit is set to 1 by hardware to indicate that the flush cycle initiated when
the Flush Control bit (HDBAR + 08h, bit 1) was set has completed. Software must write a 1 to clear
this bit before the next time the Flush Control bit is set to clear the bit.
