LMX2582: Chage MUXout pin mode after start up.

Part Number: LMX2582

Dear team, 

When the LMX2582 is initialized, we use MUXOUT as the Lock signal output, so the SPI is configured as a three-wire, and there is no register readback function. Can I configure MUXout to MUXOUT_SEL = 0 after the chip initialization is completed to read back the value of the register, and measure the read value through an oscilloscope? Thanks.
