These bits are Read/Write.
Sensed bits meaning relates to the I/O being sense as output or inputs.
Sensed bits (outputs): See Table 27: page75.
Sensed bits (inputs): See Table 28: page76.
This field is Read Only.
Order Bits. These bits indicate the order the sense result bits SR[5:0] are using.

Sense Result bits
These bits are used to report a vendor specific fingerprint or value. (Resistance,
impedance, reactance, etc.) This field is Read Only.
This field allows for the reporting of the type of output peripheral/device plugged
in the jack. Values specified below should be interrogated in conjunction with
the SR[5:0] and OR[1:0] bits for accurate reporting.
