μs Ticker: Clock peripheral with at least microsecond resolution that Mbed uses to implement Timer and Ticker.
Watchdog: Peripheral which resets the chip if software doesn't service it within a configurable amount of time. Used to guard against software hangs.
Low-Precision Ticker: Also known as the Low-Power Ticker, this peripheral keeps time at a low-frequency clock (usually 32kHz) and generates events for the application. Usually it is used to implement low power sleep.
Sleep: Support for sending the processor to sleep when no threads/ISRs are executing.
Flash IAP: Driver allowing In-Application Programming (IAP) of the MCU flash memory.
