My friend is using AD9739 in multi-sync configuration.
Sometimes the master AD9739 fail at start-up.
At step-20 in table-32 of datasheet, master AD9739 return 0xB0 instead of 0x90 when it failed.
Then we tried to read the status fron 0x15 to 0x18 registers to identify the state of sync controller.
But these registers returned following data.
0x15 : 0x42 / 0x16 to 0x18 : 0x00
These returned values are as same as when AD9739 started correctly.
We can read from 0x19 to 0x1C. Followings are returned value.
0x19 : 0xC7 / 0x1A : 0x29 / 0x1B : 0xC7 / 0x29
0x19 : 0xC7 / 0x1A : 0x2B / 0x1B : 0xC7 / 0x2B
How can we read the status correctly from 0x15 to 0x18 registers ?
