1.
COLDRSTN asserted by external logic.
2.
The RC32351 asserts RSTN, asserts BOEN[0] low, drives BDIRN low, and tri-states the data bus in response.
3.
External logic begins driving valid boot configuration vector on the data bus, and the RC32351 starts sampling it.
4.
External logic negates COLDRSTN and tri-states the boot configuration vector on MDATA[15:0]. The boot configuration vector must not be
tri-stated before COLDRSTN is deasserted. The RC32351 stops sampling the boot configuration vector.
5.
The RC32351 starts driving the data bus, MDATA[31:0], deasserts BOEN[0] high, and drives BDIRN high.
6.
SYSCLKP may be held constant after this point if Hold SYSCLKP Constant is selected in the boot configuration vector.
7.
RSTN negated by RC32351.
8.
CPU begins executing by taking MIPS reset exception, and the RC32351 starts sampling RSTN as a warm reset input.
