GetOTPparam
This command is provided to the circuit by the LIN master
after a preparing frame (see Preparing frames), to read the
content of an OTP memory segment which address was
specified in the preparation frame.
GetOTPparam corresponds to a LIN in−frame response with 0x3D indirect ID.
1. The master sends a type #7 preparing frame. After the type#7 preparing frame, the master sends a reading frame
type#6 to retrieve the circuit’s in−frame response.

2.) The master sends a type #8 preparing frame. After the type#8 preparing frame, the master sends a reading frame type#6
to retrieve the circuit’s in−frame response.
