Wiper
Each tap point (between the RS resistors) is a
connection point for an analog switch. The opposite
side of the analog switch is connected to a common
signal which is connected to the Terminal W (Wiper)
pin.
A value in the volatile wiper register selects which
analog switch to close, connecting the W terminal to
the selected node of the resistor ladder.
The wiper can connect directly to Terminal B or to
Terminal A. A zero-scale connections, connects the
Terminal W (wiper) to Terminal B (wiper setting of
000h). A full-scale connections, connects the Terminal
W (wiper) to Terminal A (wiper setting of 100h or 80h).
In these configurations the only resistance between the
Terminal W and the other Terminal (A or B) is that of the
analog switches.
A wiper setting value greater than full-scale (wiper
setting of 100h for 8-bit device or 80h for 7-bit devices)
will also be a Full-Scale setting (Terminal W (wiper)
connected to Terminal A). Table 5-1 illustrates the full
wiper setting map.
Equation 5-2 illustrates the calculation used to deter-
mine the resistance between the wiper and terminal B.
