CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Serial Interface)
(4) SIOF signal
The SIOF signal can be output from the R11 terminal regardless of the set mode, master or slave, by
mask option.
For example, when the serial interface is used in slave mode (external clock mode), the SIOF signal is
used to notify the master (external) serial device whether the internal serial interface is ready to
transmit/receive data or not. In master mode, the serial interface operating status can be checked by
reading the status bit SIOF (2ECHD1).
The SIOF signal and the SIOF bit (2ECHD1) go "1" (high) when the S1C60N16 serial interface
becomes ready to transmit/receive data; normally they are "0" (low).
The SIOF signal and the SIOF bit (2ECHD1) change from "0" to "1" immediately after "1" is written to
the SCTRG bit and return from "1" to "0" when eight synchronous clocks (eight cycles) have been
counted.
