... The MAXQ core has the industry’s best MIPS/mA rating, allowing developers to achieve the same performance as competing microcontrollers at substantially lower clock rates. Lower active-mode cur- rent combined with the even lower MAXQ612/MAXQ622 stop-mode current results in increased battery life.

... 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 ...

... The maximum SPI master transfer rate is Sysclk/2. When operating as an SPI slave, the MAXQ612/MAXQ622 can support up to Sysclk/4 SPI transfer rate. Data is trans- ferred as an 8-bit or 16-bit value, MSB first. In addition, the SPI module supports configuration of an active SSEL state through the slave active select ...
