14.3 Resume Reset Logic
The RSMRST# (Pin 75) signal is a reset output and is used as the 3VSB power-on reset signal for the
South Bridge.
When the W83627DHG detects the 3VSB voltage rises to “V1”, it then starts a delay – “t1” 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 Figure 14.5 and Table 14.2.
