2.3.3 Attenuator Operation End Flag Output of the Digital-Filter Section
When using a command to control the DF block mute ON/OFF (command-44h, bit5), the mute end flag is output from the IFOK pin after the mute operation
completes.
Moreover, when the amount of attenuators by DF attenuator command (command-58h) is changed, IFOK terminal is set to “L” level as a flag which attenuator
operation completed.
Note
At power on, the IFOK pin output is undefined. When the CS signal goes Low, the IFOK signal goes High.
