1.
The COLDRSTN minimum pulse width is the oscillator stabilization time (OSC) plus 0.5 ms with V
cc
stable.
2.
The values for this symbol were determined by calculation, not by testing.
3.
RSTN is a bidirectional signal. It is treated as an asynchronous input.

1.
COLDRSTN asserted by external logic.
The RC32438 asserts RSTN, asserts BOEN low, drives BDIRN low, disables EXTCLK, and tri-states the data
bus and all output pins in response.
2.
External logic begins driving valid boot configuration vector on the data bus, and the RC32438 starts sampling it.
3.
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 negated. The RC32438 stops sampling the boot configuration vector.
4.
The RC32438 starts driving the data bus, MDATA[15:0], negates BOEN, drives BDIRN high, and starts driving EXTCLK.
5.
RSTN negated by the RC32438.
6.
CPU begins executing by taking MIPS reset exception, and the RC32438 starts sampling RSTN as a warm reset input.
