WebJul 28, 2024 · Description. Upon signaling resume, the device is expected to allow full 3 ms of time to the host or hub for sending the initial SOF (start of frame) packet, without triggering SUSP interrupt. However, the device only allows two full milliseconds and unduly triggers SUSP interrupt if it receives the initial packet within the third millisecond. WebOct 27, 2012 · The ARM Cortex-M0+ on the KL25Z Freedom Board ( FRDM-KL25Z) runs up to 48 MHz. For this, the 8 MHz crystal on the board is used. A 48 MHz is required for USB communication, to have the needed oversampling on USB data lines. I have shown in my USB CDC post how such a clock is configured, using the white pre-production board.
