Chapter 6  Synchronous Communication Interface (SCI) Function 

13 

6.    Synchronous Communication Interface (SCI) Function 

 
The ML7065-033 is equipped with a synchronous communication interface (SCI) as the host interface.  SCI is 
available for a slave mode only.    The interrupt pin, SINT, is used for reading data from the ML7065-033 to the host. 
 
Waveform definition: 
The SCI that is incorporated in the ML7065-033 is applied to a slave mode only and the input clock from the host is 
applied to the rising edge only.   
Two types of transmit/receive data formats are available for selection, big endian and little endian.    Set a mode using 
the MODE pin.    Note that the frequencies of SCLK in a suspended state are restricted.     
Refer to Section 8.6, “Synchronous Communication Interface (SCI) Characteristics.”
