Socket Power Management Register
This register provides power management control over the socket through a mechanism for slowing or stopping the
clock on the card interface when the card is idle. See Table 67 for a complete description of the register contents.

RSVD
R
Reserved. These bits return 0s when read.
25
SKTACCES
R
Socket access status. This bit provides information on whether a socket access has occurred. This bit is
cleared by a read access.
0 = No PC Card access has occurred (default).
1 = PC Card has been accessed.
24
SKTMODE
R
Socket mode status. This bit provides clock mode information.
0 = Normal clock operation
1 = Clock frequency has changed.
2317
RSVD
R
These bits return 0s when read.
16
CLKCTRLEN
RW
CardBus clock control enable. This bit, when set, enables clock control according to bit 0 (CLKCTRL).
0 = Clock control disabled (default)
1 = Clock control enabled
151
RSVD
R
These bits return 0s when read.
0
CLKCTRL
RW
CardBus clock control. This bit determines whether the CardBus CLKRUN protocol attempts to stop or
slow the CardBus clock during idle states. The CLKCTRLEN bit enables this bit.
0 = Allows the CardBus CLKRUN protocol to attempt to stop the CardBus clock (default)
1 = Allows the CardBus CLKRUN protocol to attempt to slow the CardBus clock by a factor of 16
One or more bits in this register are cleared only by the assertion of GRST.
