Asserting the Test Reset signal forces the chip into a
Power-On-Reset state. The LSISAS1064 does not contain
an internal power-on reset circuit. This signal must be
supplied by a power-on reset circuit on the board.
This pin provides the ARM reference clock.
The Mode Select bus defines the operational and test
modes for the chip. For normal operation, pull these signals
to 0b000000.
These pins provide general purpose input/output signals.
These pins have internal pull-ups and default to input mode
upon device reset.
The active LOW Fault LED signals are nominally configured
to indicate a SAS link fault for each respective phy.
The active LOW Activity LED signals are nominally
configured to indicate SAS link activity.
The active LOW Heart Beat LED signal is nominally
configured to intermittently assert, which indicates that the
IOP is operational.
The Frequency Select signal supports clocking
configuration options for internal clocks. This signal is
reserved for diagnostic purposes.
