The RSMRST# (Pin 75) signal is a reset output and is used as the 5VSB power on reset signal for the South
Bridge.
When the W83627UHG detects the 5VSB voltage rises to “V1”, it then starts a delay – “t1” before the rising edge
of RSMRST# asserting. If the 5VSB voltage falls below “V2”, the RSMRST# de-asserts immediately.
Timing and voltage parameters are shown in Figure 13-3 and Table 13-3.
