1. Modifying the default configurations is possible only if the external RCON pin is asserted.
2. The D[31:29, 27, 25:24, 20, 15:0] pins do not affect reset configuration.
3. The external reset override circuitry drives the data bus pins with the override values while RSTOUT is asserted. It must
stop driving the data bus pins within one CLKOUT cycle after RSTOUT is negated. To prevent contention with the external
reset override circuitry, the reset override pins are forced to inputs during reset and do not become outputs until at least
one CLKOUT cycle after RSTOUT is negated.
