[Specification

This function converts a TSSI value to dBm (in Q5.2).

A PHYs

  1. Take the idle TSSI target, add the TSSI value, and then subtract the saved value of the power control register value
  2. Add 0x80 to that value and clamp between 0 and 0xFF and use this as an index into the TSSI to DBM Table

  3. Find the power out value for the current channel (based on what? It's a magic number here ... FIXME) and add that to the retrieved value

  4. Return the result

B/G PHYs

  1. Take the idle TSSI target, add the TSSI value, and then subtract the saved value of the power control register value
  2. Clamp this value between 0 and 0x3F and use this as an index into the TSSI to DBM Table

  3. Return the retrieved value, a dBm value in Q5.2
