334 / 437 page ![]() Host Controller Interface Modules (Continued) www.national.com 334 Revision 1.07 5.5.7 Usage Hints PWUREQ Output Connection The PWUREQ concentrates a set of wake-up and other power management events in the PC87591x. In typical use, this signal is connected to one of the chipset inputs that drive SCI event to the host. RESET2 Events When RESET2 is used to reset the host domain, some of the MSWC functions may need to be set to their default values when a falling edge of the RESET2 is detected. An interrupt routine triggered by this event may be used for this task. The following functions should be reset: ● GA20 ● KBRST ● Host Registers: WK_EN0, WK_SMIEN0 and WK_IRWEN0; Use the “Core Access to Host-Controlled Modules” for this operation (see Section 5.4 on page 313). |
