FUNCTIONAL DESCRIPTION
Serial Interface
The serial interface inputs various commands and data by CS, SCK, and DI pin.
The micro-computer interface becomes effective when CS pin is set to “L” level.
To input the commands and data, “L” level is input to CS pins followed by, from MSB, to DI pin in synchronization
with the input clock signal at SCK pin. Data at DI pin is captured inside the device on the rising or falling edge of the
clock at SCK pin. And the command is executed on the rising or falling edge of eight clocks of a SCK pin.
The selection of rising/falling edge of SCK clock is determined by the DIPH pin. If the DIPH pin is at “L” level, the
DI pin data is captured inside the device on the rising edge of SCK clock. Conversely, if DIPH pin is at “H” level,
then the DI pin data is captured on the falling edge of SCK clock.
Even if it makes CS pin “L” level fixation, the input of command data is possible. However, when pulses other than
specification are inputted into a SCK pin, LSI does not operate normally. The count of the number of clocks of a
SCK pin returns to an initial state by making CS pin into “H” level.
