47 * BBP and RF register require indirect register access,
48 * and use the CSR registers BBPCSR and RFCSR to achieve this.
49 * These indirect registers work with busy bits,
50 * and we will try maximal REGISTER_BUSY_COUNT times to access
51 * the register while taking a REGISTER_BUSY_DELAY us delay
52 * between each attampt. When the busy bit is still set at that time,
53 * the access attempt is considered to have failed,
54 * and we will print an error.
