/*
 * Some registers, such as the battery status register (0x41), are in
 * big-endian, but others only have eight significant bits, which are in the
 * first byte transmitted over I2C (the MSB of the big-endian value).
 * This convenience function converts an 8-bit value to 16-bit for use in the
 * second kind of register.
