pub(crate) const WAKE_TOKEN_FREQ_HZ: u32 = 100_000;Expand description
I2C bus frequency used only for the wake token. CryptoAuthLib drops to 100 kHz so a single byte time on the bus (~90 us address phase) exceeds the chip’s tWLO of 60 us. At 400 kHz an address byte is too short to be seen as a wake token, hence the temporary slowdown.
