/// Note that 7-bit addresses defined by drivers should be specified in **right-aligned** form,
/// e.g. in the range `0x00..=0x7F`.

/// For example, a device that has the seven bit addresses of `0b011_0010`, and therefore:
///
/// * `0b0110010_0` or `0x64` for *writes*
/// * `0b0110010_1` or `0x65` for *reads*
///
/// Should be specified as `0b0011_0010` or `0x32`, NOT `0x64` or `0x65`.
