watchdog timer (WDT+)
The primary function of the WDT+ 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.
Basic Timer1 and Real-Time Clock
The Basic Timer1 has 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. The Basic Timer1 is extended to provide an integrated real-time
clock (RTC). An internal calendar compensates for month with less than 31 days and includes leap year
correction.
LCD_A driver with regulated charge pump
The LCD_A driver generates the segment and common signals required to drive an LCD display. The LCD_A
controller has dedicated data memory to hold segment drive information. Common and segment signals are
generated as defined by the mode. Static, 2-MUX, 3-MUX, and 4-MUX LCDs are supported by this peripheral.
The module can provide a LCD voltage independent of the supply voltage via an integrated charge pump.
Furthermore, it is possible to control the level of the LCD voltage and, thus, contrast in software.
Timer_A3
Timer_A3 is a 16-bit timer/counter with three capture/compare registers. Timer_A3 can support multiple
capture/compares, PWM outputs, and interval timing. Timer_A3 also has extensive interrupt capabilities.
Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare
registers.
