Global reset-only bits, as the name implies, are cleared only by GRST. These bits are never cleared by PRST, regardless of the setting of the PME enable bit. The GRST signal is gated only by the SUSPEND signal. This means that assertion of SUSPEND blocks the GRST signal internally, thus preserving all register contents. Figure 3−13 is a diagram showing the application of GRST and PRST.
