13.2.2
The mouse Wake-Up function is enabled by setting Logical Device A, CR[E0h], bit 5 to “1”.
The following specific mouse events can be used for the wake-up:
Three control bits (ENMDAT_UP, MSRKEY, MSXKEY) define the combinations of the mouse wake-up
events. Please see the following table for the details.
13.3 Resume Reset Logic
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.
