7.18 Power Management Control and Status Register
The power management control and status register implements the control and status of the Smart Card controller.
This register is not affected by the internally generated reset caused by the transition from the D3
hot
to D0 state. See
Table 713 for a complete description of the register contents.

DESCRIPTION
15
PME_STAT
RCU
PME status. This bit defaults to 0.
1413
DATA_SCALE
R
This field returns 0s, because the data register is not implemented.
129
DATA_SELECT
R
This field returns 0s, because the data register is not implemented.

PME_EN
RW
PME enable. Enables PME signaling. assertion is disabled.

RSVD
R
Reserved. Bits 72 return 0s when read.
10
PWR_STATE
RW
Power state. This 2-bit field determines the current power state and sets the Smart Card controller to
a new power state. This field is encoded as follows:
00 = Current power state is D0.
01 = Current power state is D1.
10 = Current power state is D2.
11 = Current power state is D3hot.
One or more bits in this register are cleared only by the assertion of GRST.
7.19 Power Management Bridge Support Extension Register
The power management bridge support extension register provides extended power-management features not
applicable to the Smart Card controller; thus, it is read-only and returns 0 when read.
