Command bit
SFP3 to 0
Sets the frame sync forward protection times. The setting range is 1 to F (Hex).
Processing
• The CXD3068Q can serially output the 40 bits (10 BCD codes) of error monitor data selected by EDC0 to 7
from the SQSO pin and monitor this data using a microcomputer.
The C1 and C2 error rate settings are sent one at a time by the $C commands by setting $8 commands
SOCT0 and SOCT1 = 1. Then, the data can be read out from the SQSO pin by sending 40 SQCK pulses.
