To get a fast information of the received protocol, after every power on the received signal will be compared
with the chosen protocol. The bit stream is checked for pulses with characteristically pulse duration.
To start a new protocol recognition it is necessary to reset via PON.
Three bits are output on Data_Out pin when the protocol is detected. Output on Data_Out pin is specified in
the table “Logical function of SS1, SS2” (page 9).
WWVB is designed such that when S1, S2 selected WWVB, CME8000 scans automatically in parallel the 3
possibilities in JJY, WWVB and MSF. Once protocol identified is not WWVB, user should switch to its correct
protocol setting and confirm once again on the correct setting in 60kHz.

Output as binary digital output on BSI1 and BSI2
Bit strength indication
The pins BSI2 and BSI1 are the output pins for the bit strength indication with 4 levels. The bit strength
indication is only influenced by the quality of the received bit and not of the field strength.
The bit strength indication starts after every power on at 0. So the outputs will be updated every second.
