摘要
In an embodiment, a method of operating a radar includes: transmitting a radiation pulse with the radar during an active mode; asserting a sleep flag after transmitting the radiation pulse; turning off a crystal oscillator circuit of the radar after the sleep flag is asserted; clocking a counter of the radar with a low power oscillator during a low power mode after the sleep flag is asserted; asserting a timer flag when the counter reaches a first threshold; and transitioning into the active mode after the timer flag is asserted.
