NOTES:
1. The JTAG (TDO, TMS, TCLK, TRST, and TDI) and I2C (SCLK and SDAT) signals share the same pins with GIN signals.
2. Internal weak pull-down.
3. 3-level inputs are static inputs and must be tied to VDD or GND or left floating. These inputs are internally biased to VDD/2. They are not hot-insertable or over voltage tolerant.
4. Outputs are user programmable to drive single-ended 3.3V LVTTL, differential LVDS, or differential LVPECL interface levels.
