Description
Reserved. By convention write 0, but may write anything.
Sleep Y De-assert and Delay Enable. Must be high to de-assert SLEEP_Y and
enable the delay specified in bits [29:0] (SLPY_END_DELAY).
Sleep Control Y De-assert Delay. Indicates the number of 3.57954 MHz clock edges
to wait from Sleep wakeup before de-asserting the SLEEP_Y ball. Bit 30
(SLPY_END_EN) must be high to enable this delay.
If PCI_IDE_IN_SLP is not enabled (PMS I/O Offset 20h[30] = 0) or is less than the
SLPY_END_DELAY, SLEEP_Y de-asserts at the same time the PCI/IDE inputs are re-
enabled.
