REGISTER DESCRIPTIONS AND MEMORY MAP
Memory Map
Wiper Counter Register (WCR)
WP0 - WP5 identify wiper position.
Data Registers (DR, R0 - R3)
Instruction Format
Notes: (1) “A1 ~ A0”: stands for the device addresses sent by the master.
(2) WPx refers to wiper position data in the Wiper Counter Register
(3) “I”: stands for the increment operation, SI held HIGH during active SCK phase (high).
(4) “D”: stands for the decrement operation, SI held LOW during active SCK phase (high).
Read Wiper Counter Register (WCR)
Read the contents of the Wiper Counter Register pointed to by P1 - P0
Write Wiper Counter Register (WCR)
Write new value to the Wiper Counter Register pointed to by P1 - P0
Read Data Register (DR)
Read the contents of the Register pointed to by P1 - P0 and R1 - R0
Write Data Register (DR)
Write new value to the Register pointed to by P1 - P0 and R1 - R0
