Power Management Module (PMM) (Link to user's guide)

The PMM includes an integrated voltage regulator that supplies the core voltage to the device and contains

programmable output levels to provide for power optimization. The PMM also includes supply voltage supervisor

(SVS) and supply voltage monitoring (SVM) circuitry, and brownout protection. The brownout circuit is

implemented to provide the proper internal reset signal to the device during power-on and power-off. The SVS

and SVM circuitry detects if the supply voltage drops below a user-selectable level and supports both supply

voltage supervision (the device is automatically reset) and supply voltage monitoring (the device is not

automatically reset). SVS and SVM circuitry is available on the primary supply and core supply.

Hardware Multiplier (Link to user's guide)

The multiplication operation is supported by a dedicated peripheral module. The module performs operations with

32-bit, 24-bit, 16-bit, and 8-bit operands. The module is capable of supporting signed and unsigned multiplication

as well as signed and unsigned multiply and accumulate operations.

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 or counter. Both timers can be read and written by software. Calendar

mode integrates an internal calendar that 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 watchdog timer (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.
