49 * BBP and RF register require indirect register access,
50 * and use the CSR registers BBPCSR and RFCSR to achieve this.
51 * These indirect registers work with busy bits,

53 * the register while taking a REGISTER_BUSY_DELAY us delay
54 * between each attampt. When the busy bit is still set at that time,
55 * the access attempt is considered to have failed,
