44       Optional bi-directional line that allows SPI master to indicate to SPI
46       the latter can prepare (and indicate its readiness) for handling that
47       transfer when it is actually needed, and stay in any desired low-power
50       - initially, SPI slave configures its WAKE line pin as an input and SPI
51         master keeps the line in the low state
52       - when a transfer is to be performed, SPI master configures its WAKE
53         line pin as an input with pull-up; this changes the line state to
55       - when SPI slave detects the high state of the WAKE line, it prepares
58       - the generated high-to-low transition on the WAKE line is a signal
59         to SPI master that it can proceed with the transfer
60       - SPI slave releases the line by configuring its pin back to be an input
61         and SPI master again keeps the line in the low state
