Figure 7.

Successful power-up on STM6600 (PB released prior to tON_BLANK expiration)

PB detection on falling and rising edges.

Internal pull-down resistor 300 k

Ω is connected to PSHOLD input during power-up.

EN signal is high even after PB release, because processor sets PSHOLD signal high before PB is released.

INT signal is held high during power-up (i.e. until PB release in this case).

CC is considered VCC > VTH+.
