11.18 Power Management Control and Status Register

The power management control and status register implements the control and status of the flash media controller. This register is not affected by the internally generated reset caused by the transition from the D3hot to D0 state. See Table 11−13 for a complete description of the register contents.

Power state. This 2-bit field determines the current power state and sets the flash media controller to

a new power state. This field is encoded as follows:

1−0 ‡

PWR_STATE

RW

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.

11.19 Power Management Bridge Support Extension Register

The power management bridge support extension register provides extended power-management features not applicable to the flash media controller; thus, it is read-only and returns 0 when read.
