IFOK pin description
The IFOK signal has the following three functions.
(4-1) ACMP mode end flag output
After the completion of a RAM data update with CRAM-ACMP (CMD: 47h) or OFRAM-ACMP
(CMD: 49h), the IFOK pin goes Low. Setting the CS signal to Low changes the IFOK signal
from Low to High.
Example:
(4-2) Loading end flag output in Monitor mode
When monitoring using the bus monitor command (CMD: 50h), for example, after data are loaded
to the internal register under the specified conditions, the IFOK signal goes Low. In monitor
mode, when the CS signal goes High, the IFOK signal also goes High.
Example:
(4-3) Mute end flag output for digital filter (DF) block
When using a command to control the DF block mute on/off (CMD: 36h, bit 5), the mute end flag
is output from the IFOK pin after the mute operation completes.
Example:
Note 1: At power on, the IFOK pin output is undefined. When the CS signal goes Low, the
IFOK signal goes High.
