Wiper Counter Register, (6-Bit), Volatile
One 6-bit wiper counter register for each XDCP. (Four
6-bit registers in total.)
– {D5~D0}: These bits specify the wiper position of the
respective XDCP. The Wiper Counter Register is
loaded on power-up by the value in Data Register 0.
The contents of the WCR can be loaded from any of
the other Data Register or directly. The contents of
the WCR can be saved in a DR.
Instruction Format
Notes: (1) “MACK”/”SACK”: stands for the acknowledge sent by the master/slave.
(2) “A3 ~ A0”: stands for the device addresses sent by the master.
(3) “X”: indicates that it is a “0” for testing purpose but physically it is a “don’t care” condition.
(4) “I”: stands for the increment operation, SDA held high during active SCL phase (high).
(5) “D”: stands for the decrement operation, SDA held low during active SCL phase (high).
