Description
Secondary Bus Central Function Control Pin. When
tied LOW, it enables the internal arbiter. When tied
HIGH, an external arbiter must be used. S1_REQ#[0]
or S2_REQ#[0] is reconfigured to be the secondary bus
grant input, and S1_GNT#[0] or S2_GNT#[0] is
reconfigured to be the secondary bus request output.
Description
Primary Clock Input. Provides timing for all
transactions on the primary interface.
Secondary Clock Output. Provides secondary 1
clocks phase synchronous with the P_CLK.
Secondary Clock Output. Provides secondary 2
clocks phase synchronous with the P_CLK.
Description
Reserved. Reserved for future use. Must be tied
HIGH.

Reserved. Reserved for future use. Must be tied
LOW.
Full-Scan Test Mode Enable (Active LOW).
Connect HIGH for normal operation.
When SCAN_TM# is active, the ten scan chains will be
enabled. The scan clock is P_CLK. The scan input and
outputs are as follows:
S1_REQ[6], S1_REQ[5], S1_REQ[4], S1_REQ[3],
S1_REQ[2], S2_REQ#[6], S2_REQ#[5], S2_REQ#[4],
S2_REQ#[3], S2_REQ#[2], and S1_GNT#[6],
S1_GNT#[5], S1_GNT#[4], S1_GNT#[3],
S1_GNT#[2], S2_GNT#[6], S2_GNT#[5],
S2_GNT#[4], S2_GNT#[3], S2_GNT#[2]
Full-Scan Enable Control. SCAN_EN should be tied
LOW in normal mode. When SCAN_EN is LOW, full-
scan is in shift operation if SCAN_TM# is active.
When SCAN_EN is HIGH, full-scan is in parallel
operation if SCAN_TM# is active.
Description
Hot Swap LED. The output of this pin lights a blue
LED to indicate insertion and removal ready status. If
HS_EN is LOW, pin is S2_GNT#[7].
Hot Swap Switch. When driven LOW, this signal
indicates that the board ejector handle indicates an
insertion or impending extraction of a board. If HS_EN
is LOW, pin is S2_REQ#[7].
Hot Swap Enable. To enable Hot Swap Friendly
support, this signal should be pulled HIGH.
