Tag for Unsolicited Response.
Tag [5:0] is defined by software to assign a 6-bit tag for nodes that are enabled to generate unsolicited
responses.
A node enabled to generate unsolicited responses must return the assigned tag in the top six bits of every
unsolicited response. According to the returned tag, software can identify which node generated the
unsolicited response.
Description
0: No device is attached to the pin
1: Device is attached to the pin
Measured Impedance.
0x7FFFFFFF or 0xFFFFFFFF: Valid sense is not available or busy.
Description
Not supported (returns 00000000h).
