Analog Devices Integer-N PLL: How do I use the SDOUT (serial data output) function of MUXOUT on the ADF4116?

RF and microwave

Set MUXOUT to "serial data output". SDOUT now transmits the previously written register data.
 
Working example:
・Set MUXOUT to serial data output
Write register R0.
• Write register R1.
During this write, MUXOUT transmits the contents of R0.
 
• Write register R2.
During this write, MUXOUT transmits the contents of R1.
A register read operation cannot be performed without concurrent writes.
