SCK
Control Register Serial Data Sift Clock Input Terminal
I
Control register leads the control data synchronizing the rising edge of SCK
signal. When the control register is not used, the state of SCK terminal has to
keep level ”H”.
4
DATA
Control Register Serial Data Input Terminal
I
Input data sets various functions.
When the control register is not used, the state of DATA terminal has to keep level
“H”.
5
REQ
Control Register Serial Data Request Input Terminal
The control data are latched in the control register at the rising edge of REQ
I
signal.
When the control register is not used, the state of REQ terminal has to keep level
“H”.
