Read returns zero.
Polarity Reversal Status.
0 = Forward polarity.
1 = Reverse polarity.
Wink Function Control.
Enables a wink function by decrementing the open circuit voltage to zero.
0 = Maintain current V
1 = Decrement V
Smooth Polarity Reversal Enable.
0 = Disabled.
1 = Enabled.
Smooth Polarity Reversal Ramp Rate.
0 = 1 V/1.25 ms ramp rate.
1 = 2 V/1.25 ms ramp rate.
A write to RAMDAT followed by a write to RAMADDR places the contents of RAMDAT
into a RAM location specified by the RAMADDR at the next memory update (WRITE
operation). Writing RAMADDR loads the data stored in RAMADDR into RAMDAT only at
the next memory update (READ operation).
