Case 2: Sleep Mode
After power-up or when PWDN transitions from low to
high, the serializer starts up in sleep mode. To wake up
the serializer, use the FC to send a GMSL protocol UART
frame containing at least three rising edges (e.g., 0x66),
at a bit rate no greater than 1Mbps. The low-power wake-
up receiver of the serializer detects the wake-up frame
over the reverse control channel and powers up. Reset
the sleep bit (SLEEP = 0) of the serializer using a regular
control-channel write packet to power up the device fully.
Send the sleep bit write packet at least 500Fs after the
wake-up frame. The serializer goes back to sleep mode
if its sleep bit is not cleared within 5ms (min) after detect-
ing a wake-up frame.
