MCLK supply for AD7767-1

Dear Support team,

I would like to AD conversion processing in synchronization with the external pulse.
Is there a problem in the following procedure specifically?

1. MCLK port holds Low state until receive synchronization pulse from external.
2. When AD7767-1 receives synchronization pulse from the external, supplies the MCLK (16 pulses), and performs AD conversion processing.
3. Repeat step 1 and 2.
