A ready flag that is always false

Bit 8 of STATUS is set, yet ready is 0. Why, and what fixes it?

uint8_t ready = STATUS & (1u << 8);

A.0x100 is cut to 8 bits, giving 0; use != 0 to get 1B.Bit 8 cannot be read from a 32-bit registerC.The & operator returns only bit 0D.STATUS must be declared const first
