Fig. 17 Transmission memory data write  
1) This command transmits the wiper position data to the addresses specified by A0 to A6. The data from the seven  
bits D8 to D14 of the specified address are stored in the memory during the time tE / W, starting from the rise of the  
16th clock.  
2) Writing is done to the internal non-volatile memory during the time when this command is input and automatic  
writing of the data is completed. Commands input during this time will not be accepted. The maximum time for this  
period must be within tE / W.  
3) After the write command has been input, if CS is set to LOW after having been set to HIGH, command reception  
is enabled following termination of the automatic data writing. Data can then be received from SK and DIO. If CS is  
left at LOW following input of the command, however, without being set to HIGH, input of the command is canceled.

1) The wiper position is incremented or decremented starting from the next clock following input of the INC / DEC  
command, based on the status of the INC pin.  
DIO = H: Incremented. The wiper position moves from the VL to the VH side by 1 tap per clock.  
DIO = L: Decremented. The wiper position moves from the VH to the VL side by 1 tap per clock.  
2) The tap is moved at each rise of the clock, until CS is set to HIGH.  
When the tap is farthest to the VH side, incrementing is ignored.  
In the same way, when the tap is farthest to the VL side, decrementing is ignored.
