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.
Figure 5-654 shows the PGD block diagram.
A flag status bit in corresponding STAT register is cleared by clearing the [30] RSTB bit in the corresponding CTRL register, see for STAT and CTRL registers for a certain PGD module.
