Function
Reference Resistor Connection. An off-chip 3.16 k
±1% resistor is connected between these the positive
resistor reference pin RES and a Kelvin ground contact
RESK. An on-chip negative feedback path will force the
1.20 V VREF Voltage onto RES, therefore forcing 252
µA of current to flow through the resistor.
Analog test bus for PMC validation and testing.
This pin must be connected to GND.
Analog test bus for PMC validation and testing.
This pin must be connected to GND.
The digital core power pins (VDDI[44:0]) should be
connected to a well-decoupled +1.8 V DC supply.
