A Power Glitch Detect (PGD) circuit is used to detect short duration “glitches” on the core and MPU power supplies. The PGD provides a low output when no glitch is detected and a high output when a glitch is detected.
Table 5-833 shows PGD modules allocation within device domains.

Figure 5-405 shows the PGD block diagram.
Table 5-834 summarize the PGD integration.
