I used 12Mhz as reference clock and followed the AN1070 to send the command. But the IC didn’t output the clock. It remind at high level. The IC need to wait 5 minutes to start output clock. After IC started to output clock, I could use the command to change the frequency. Here is more information about my setup. Does anybody help to figure it out?
Initialization Command : 0x2100,0x4444,0x4111,0xc000,0x2000, expect to have 200khz
MCU: ATmega64 (ATMEL)
