Signal Descriptions
This section describes the signals of "Vega 10".
The following conventions are used:
•
All active low signals are shown with the suffix “B”, such as CASA0B.
•
“PD” denotes a permanent internal pull down. “PD-register” denotes an internal
pull down which is register controlled, and by default is turned off. “PD-reset”
denotes an internal pull down which is register controlled, and by default is
turned on. “PD-reset” also denotes that the internal pull down is active during
reset. “PD” or “PD-reset” is not relevant when the pins are in output modes.
•
To designate a group of pins that have the same pin name but are distinguished
by a trailing number only, such as QSA_0, QSA_1, or QSA_2, the abbreviation
“Pin name[y:x]” is used. For example, QSA_[7:0] means pins QSA_7 to QSA_0.
•
In the "Vega 10" pin assignment:
•
NC or NC_*: Pins marked as NC are free pins that have no electrical
connection on the GPU package.
•
RSVD: These pins should float (i.e., no electrical connection) on the PCB.
