>= 4096 CLKP clock cycles

(RSTN ignored during this period
to allow pull-up to drive signal high)
*
Selection of 4096 or 64 cycles is selected by the boot configuration vector (fast reset).
1.
Warm reset condition caused by either RSTN asserted, write to reset register, or bus transaction timer time-out. The RC32351 asserts RSTN out-
put low in response.
2.
The RC32351 tri-states the data bus, MDATA[31:0], and deasserts all memory control signals, such as RASN, CASN, RWN, OEN, etc.
3.
The RC32351 deasserts RSTN.
4.
The RC32351 starts driving the data bus, MDATA[31:0], again, but does not sample the RSTN input.
5.
CPU begins executing by taking a MIPS soft reset exception and also starts sampling the RSTN input again.
