Description
VN, VP
1, 2
Dedicated analog input channel for the XADC.
XADC_VAUX0P, N
3, 6
Auxiliary analog input channel 0. Also supports use as IO inputs when anti
alias capacitor is not present.
XADC_VAUX8N, P
7, 8
Auxiliary analog input channel 8. Also supports use as IO inputs when anti
alias capacitor is not present.
DXP, DXN
9, 12
Access to thermal diode.
XADC_AGND
4, 5, 10
Analog ground reference.
XADC_VREF
11
1.25V reference from the board.
XADC_VCC5V0
13
Filtered 5V supply from board.
XADC_VCC_HEADER
14
Analog 1.8V supply for XADC.
VADJ
15
VCCO supply for bank which is the source of DIO pins.
GND
16
Digital Ground (board) Reference
XADC_GPIO_3, 2, 1, 0
19, 20, 17, 18
Digital IO. These pins should come from the same bank. These IOs should not
be shared with other functions because they are required to support three-state
operation.
