Hardware Multiplier
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_B)
The RTC_B module contains an integrated real-time clock (RTC) (calendar mode). Calendar mode integrates an
internal calendar which compensates for months with less than 31 days and includes leap year correction. The
RTC_B also supports flexible alarm functions and offset-calibration hardware. RTC operation is available in
LPM3.5 modes to minimize power consumption.
Watchdog Timer (WDT_A)
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.
System Module (SYS)
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, boot strap
loader entry mechanisms, as well as, configuration management (device descriptors). It also includes a data
exchange mechanism via JTAG called a JTAG mailbox that can be used in the application.
