The following example has one repeater and two FCs
(Figure 34). Table 18 summarizes the authentication
operation.

Writes REPEATER = 1 in RX_R1.
Retries until proper acknowledge
frame is received.
Note: This step must be completed
before the first part of authentica-
tion is started between TX_B1 and
RX_R1 by FC_B (step 7). To satisfy
this requirement, for example:
RX_R1 can be held at power-down
until FC_R is ready to write the
REPEATER bit.
Or, the FC_B can poll FC_R before
starting authentication.
