IFOK Pin Description
The IFOK signal has the following three functions.
2.3.1 ACMP Mode End Flag Output
After the completion of a RAM data update with CRAM-ACMP (command-47h) or OFRAM-ACMP (command- 49h), the IFOK pin goes Low. Setting the CS
signal to Low changes the IFOK signal from Low to High.
Example:
2.3.2 Loading End Flag Output in Monitor Mode
When monitoring using the bus monitor command (command-50h), for example, after data are loaded to the internal register under the specified conditions,
the IFOK signal goes Low. In this mode, if CS signal is made into “H” level, IFOK signal will also be set to “H” level.
