RC 1'b0 Radio frame pulse received. This bit is asserted every 10 ms and
remains asserted until cleared by user
logic.#nik1411442180153/fn_RC_init_reminder
(2)
This register field is a read-to-clear field. You must read the register twice to read the true value of the
field after frame synchronization is achieved. If you observe this bit asserted during link initialization,
read the register again after link initialization to confirm any errors.
