4.38 Power-Management Control/Status Register
The power-management control/status register determines and changes the current power state of the PCI1520
CardBus function. The contents of this register are not affected by the internally-generated reset caused by the
transition from D3
hot
to D0 state. All PCI, ExCA, and CardBus registers are reset as a result of a D3
hot
to D0 state
transition. TI-specific registers, PCI power-management registers, and the PC Card 16-bit legacy-mode base
address register (PCI offset 44h, see Section 4.28) are not reset. See Table 4
–
15 for a complete description of the
register contents.

BIT
SIGNAL
TYPE
FUNCTION
15
PMESTAT
RC
PME status. Bit 15 is set when the CardBus function would normally assert PME, independent
of the state of bit 8 (PME_EN). Bit 15 is cleared by a writeback of 1, and this also clears the PME
signal if PME was asserted by this function. Writing a 0 to this bit has no effect.

13
DATASCALE
R
Data scale. This 2-bit field returns 0s when read. The CardBus function does not return any
dynamic data.
12
–
9
DATASEL
R
Data select. This 4-bit field returns 0s when read. The CardBus function does not return any
dynamic data.
8
PME_EN
RW
PME enable. Bit 8 enables the function to assert PME. If this bit is cleared, then assertion of PME
is disabled.
7

2
RSVD
R
Reserved. Bits 7
–
2 return 0s when read.

0
PWR_STATE
RW
Power state. This 2-bit field is used both to determine the current power state of a function and
to set the function into a new power state. This field is encoded as:
00 = D0
01 = D1
10 = D2
11 = D3hot
