Figure 40. Reset Timing
Reset Phase 1: The RESET pin is asserted. During this time, all internal clocks are running at the CLKIN frequency
Reset Phase 2: The RESET pin is deasserted but the internal reset is stretched. During this time, all internal clocks are running at the CLKIN frequency
Reset Phase 3: Both the RESET pin and internal reset are deasserted. During this time, all internal clocks are running at their default
