When the W83627EHF/EHG/EF/EG detects the 3VSB voltage rises to “V1”, it then starts a delay – “t”
before the rising edge of RSMRST# asserting. If the 3VSB voltage falls below “V2”, the RSMRST#
de-asserts immediately.
Timing and voltage parameters are shown in the following figure and table.
12.2 PWROK Generation
The PWROK (Pin 71) signal is an output and is used as the 3VCC power-on reset signal.
When the W83627EHF/EHG/EF/EG detects the 3VCC voltage rises to “V3”, it then starts a delay – “t2”
before the rising edge of PWROK asserting. If the 3VCC voltage falls below “V4”, the PWROK
de-asserts immediately.
Timing and voltage parameters are shown in figure and table.
