detailed description
reset-validation circuit
A reset-validation circuit has been implemented to qualify the active-high RESET input. At power up, the level
on the RST output is unknown. Whenever RESET is stable for at least eight ARBCLKIs, RST reflects the
inverted state of that stable value of RESET. Any changes on RESET must be valid for eight ARBCLKI clocks
before the change is reflected on RST. This 8-clock filter provides needed hysteresis on the master reset input.
RST is driven by a low-noise, open-drain, fail-safe output buffer.
