Real-Time Clock (RTC_A) (Link to User's Guide)
The RTC_A module can be used as a general-purpose 32-bit counter (counter mode) or as an integrated real-
time clock (RTC) (calendar mode). In counter mode, the RTC_A also includes two independent 8-bit timers that
can be cascaded to form a 16-bit timer/counter. Both timers can be read and written by software. Calendar mode
integrates an internal calendar which compensates for months with less than 31 days and includes leap year
correction. The RTC_A also supports flexible alarm functions and offset-calibration hardware.
Watchdog Timer (WDT_A) (Link to User's Guide)
The primary function of the WDT_A module is to perform a controlled system restart after a software problem
occurs. If the selected time interval expires, a system reset is generated. If the watchdog function is not needed
in an application, the module can be configured as an interval timer and can generate interrupts at selected time
intervals.
System Module (SYS) (Link to User's Guide)
The SYS module handles many of the system functions within the device. These include power-on reset and
power-up clear handling, NMI source selection and management, reset interrupt vector generators, bootstrap
loader entry mechanisms, and configuration management (device descriptors). It also includes a data exchange
mechanism through JTAG called a JTAG mailbox that can be used in the application.
