SIGNAL DESCRIPTION, INTEGRATED AUDIO MODULE (IAM)
General
All the values given below are between the respective terminal in column 1 and terminal #A14 in column 2 (power ground) unless otherwise stated in brackets after the table entry.
Note. It is important to connect the breakout box and check the ground connections before measuring.
| U= | DC voltage in volts (V) | U low = | Voltage approximately 0 V |
