The following grounds should be routed back to their respective regulators and then t ied directly to the ground plane wit h one
via: GND_PVSS, GND_MPVSS, GND_TPVSS, and GND_A2VSSN. The other ground pins (GND_AVSSN, GND_A2VSSQ,
GND_RSET, GND_R2SET) should be tied to the ground plane directly through one via as close to the pins as possible
without connecting to anything else. If space is an issue it is possible to use one via for two adjacent pins.
Use 47uF Tant. 16V 20% D size (P/N 4230047600),
800mR Max. ESR and Max. ripple 430mA @ 100kHz
or
100uF, Alum. 6.3V 20% 6.3mm dia (P/N 4261010700),
440mR Max. ESR and Max. ripple 230mA @ 100kHz
or
47uF, Alum. 6.3V 20% 5mm dia (P/N 4262047600),
760mR Max. ESR and Max. ripple 150mA @ 100kHz

The value of resistor were chosen to r educe failure rat e caused by
possible defective regulators, i.e., 33R are us e d i n s t ead of 47R or
51R for more start up current. (3.465V - 1.8V) / 33R = 50.5 m A
805 package resistor are required for sufficient power rating
(0.1W rating). (3.465V - 1.8V) * 50.5mA = 0.085W; therefore,
smaller resistor value would require 1206 package

Note that for AGP configurations GPIO(4) acts as the IDSEL strap.
For PCI it acts as the PLL bypass (33 or 66MHz) strap.
0 - VGA controller capabillity enabled.

10 - two f unction de vice. AGP only in function 0
11 - two function device. AGP in both functions
If BUSCFG pin based straps are set to PCI, then AGP will not be enabled in any function.
See AGP function table below for detail on AGP ability claims.
