All POK modules are inWKUP domain regardless of the domain of the voltage they monitor.
In this family of devices, the Power-on-reset module is used only for voltage monitoring, as three additional POK modules. For more information about POK functionality in POR module - voltage being monitored and type (under voltage or over voltage), see Power on Reset (POR) Module.

POK modules are responsible for accurately detecting the voltage levels. Each module is trimmed to account for process and temperature variations. The trim values are provided by eFuse chains enabled by a POR/Reset Generator (PRG) module.
Two types of POK modules are implemented in this family of devices - POK and POK_SA. See Table 5-31 about the type of a POK and the voltage it is monitoring. More information about the two types of POKs is given further in this section.
