HIZSTA
Resistor status bit. A high indicates that both
resistors are in high-impedance mode. A low
indicates that both resistors are operating
normally.

R/W
0HIZCO
Resistor control bit. Setting this bit high
causes both resistors to go into a high-
impedance state.

corresponding measurement in bytes 60h to
61h. This bit can be written to a 0 by the user
and monitored to verify that a conversion has
occurred.
