L848A_A
Description
Power supply for GPIO port signals. A 0.1 F ceramic capac-
itor should be connected between the VDDG pins and the
ground plane as close to the device as possible.
Ground for digital circuitry. All GND pins must be connected
together as close to the device as possible.
Ground for analog circuitry. All AGND pins and VNEG must
be connected together as close to the device as possible.
This pin should be connected to GND (this reference signal
may be connected to the +3.3 V pin on the PCI bus, even if
the PCI bus does not supply 3.3 V).
Reserved
These pins are remapped on the Bt848A and Bt849A to pro-
vide the same functionality as on the Bt848 but on a different
pin.
