The V
For device operation, the maximum signal voltage (V
There is approximately 100 mV of hysteresis on inputs using LVCMOS33 and LVCMOS25 I/O standards.
All Dedicated pins (PROG_B, DONE, TCK, TDI, TDO, and TMS) use the LVCMOS25 standard and draw power from the V
The Dual-Purpose configuration pins use the LVCMOS25 standard before the User mode. When using these pins as part of a standard 2.5V
configuration interface, apply 2.5V to the V
