Changes
#1 Changed voltage sense circuit of supervisor to sense 1.0V power rail: Replaced R7 by 10K and R15 by 19K1
Type: SCH change
Reason: XILINX recommendation use VCCINT (1.0V) for sensing.
Impact: None, reset is asserted when VCCINT is below approx 0.84V.
#2 Added series resistors (33 Ohm) to RGB led (R29 .. R31)
Type: SCH change
Reason: Improve signal integrity, avoid ringing.
Impact: None.
#3 Added pull-up resistors (10K) to SD-card (R23 .. R28 )
Type: SCH change
Reason: XILINX recommendation for SD connected without level shifter, avoid floating inputs when SD not used.
Impact: None.
#4 Added series resistors 33 Ohm (R32, R21) on CLK and MIO28
Type: SCH change
Reason: Improve signal integrity, avoid ringing.
Impact: None.
#5 Added testpoints
Type: SCH change
Reason: Prepare for automatic testing.
Impact: None, also 3.3V and GND availabe on testpoints.
#6 Added ferrit beads L1 and L2
Type: SCH change
Reason: XILINX recommendation for clean power supply of XADC.
Impact: None.
