ADVANCE INFORMATION
KILL pin is used as a control input from the host in the latched RESET version. A short press on PB pin asserts the RESET in latched version. The host pulls KILL high if RESET assert for the host has performed all the expected tasks like enabling the whole power tree. The device ignores the KILL input for tSINT + tKILL time, allowing sufficient time for host to monitor the operation. The Host pulls KILL low if RESET assert doesn't perform all expected operations. Push-button de-asserts RESET if KILL is low after debounce period as shown in Figure 6-4. Host can pull KILL low at any time to de-assert RESET without any button press. KILL input is ignored for non-latched RESET configuration. Short kill to VDD is unused.
