BBIC Clock
Adjustment
TP1
1. Execute the command "deactmac".
2. Execute the command "conttx".
3. Input Command “rdeeprom_00_00_02”, then you can confirm the current value.
4. Adjust the frequency of TP1 executing the command "setfreq 00 xx (where xx is the
value)" so that the reading of the frequency counter is 10.368000MHz ± 3Hz.
