... MIPS/mA rating, allowing developers to achieve the same performance as competing microcontrollers at substantially lower clock rates. Lower active-mode current combined with the even lower MAXQ613 stop- mode current (0.2FA typ) results in increased battery life. Application-specific peripherals include flexible timers for generating IR carrier frequencies and modulation. A ...

... The watchdog timer is a free-running counter designed to be periodically reset by the applica- tion software. If software is operating correctly, the coun- ter is periodically reset and never reaches its maximum count. However, if software operation is interrupted, the timer does not reset, triggering a system reset and optionally a watchdog timer interrupt ...
