This pin is connected to the system’s 5-volt power
supply, unless 5 volts is not available. In systems
where 5 volts is not available, this pin is
connected to the system’s 3.3-volt supply.
This pin provides power to the core circuitry of the
PD6729. It can be connected to either a 3.3- or 5-
volt power supply, independent of the operating
voltage of other interfaces. For power
conservation on a system with a 3.3-volt supply
available, this pin should be connected to the 3.3-
volt supply even if there is no intention of
operating other interfaces on the device at less
than 5 volts.
All PD6729 ground lines should be connected to
system ground.
All PD6729 ground lines should be connected to
system ground.
These pins are reserved for future expansion and
can be left unconnected. Pin 2 is an output, and
pins 3 and 208 are inputs. There is no need to tie
input pins 3 and 208 to V
This active-low output controls the 5-volt
supply to the socket’s V
active-low level of this output is mutually
exclusive with that of -VCC_3.
Speaker Output: This output can be used
as a digital output to a speaker to allow a
system to support PCMCIA card fax/
modem/voice and audio sound output. This
output is enabled by setting the socket’s
Misc Control 1 register bit 4 to a ‘1’ (for
the socket whose speaker signal is to be
directed from BVD2/-SPKR/-LED to this
pin).
LED Output: This output can be used as
an LED driver to indicate disk activity when
a socket’s BVD2/-SPKR/-LED pin has
been programmed for LED support. The
Extension Control 1 register bit 2 must be
set to a ‘1’ to enable this output as an LED
indicator for the PD6729, and a socket’s
ATA Control register bit 1 must be set to a
‘1’ to allow the level of the particular
socket’s BVD2/-SPKR/-LED pin to pass
through to the LED_OUT* pin, or a socket’s
Extension Control 1 bit 1 must be set to a
‘1’ to allow card-cycle activity to cause the
LED_OUT* pin to go active low.
