RTC module support is device part number dependent. Refer to a device-specific Data Manual, for more information.
Figure 25-3 shows the integration of the Real-time clock subsystem inside the device.

The Default Mapping column in Table 25-4, RTC Hardware Requests shows the default mapping of module IRQ source
signals. These IRQ source signals can also be mapped to other inputs of each
device Interrupt controller through the IRQ_CROSSBAR module.
For more information about the IRQ_CROSSBAR
module, see IRQ_CROSSBAR Module Functional Description, in Control
Module.
For more information about the
device interrupt controllers, see Interrupt Controllers.
