I have added the control signals DARM_CTRL, MICH_CTRL, PRCL_CTRL, SRCL_CTRL, CARM_CTRL, XARM_CTRL, YARM_CTRL, MC_CTRL to the DAFI model from the LSC model via IPC commn.
The changes done to the LSC model include addition of an extra block going to DAFI (attachment 2, red rectangle in attachment 1), and addition of an extra overall output from the LSC, called DAFI_OUT2, which goes to DAFI through IPC link C1:LSC-DAF_2 (attach. 3). Now two distinct inputs can be given to the DAFI, whose intended purpose is to act as two distinct audio signals in the stereo output, but can also be used for arbitrary math.
I am going to add the following PEM channels as DAF inputs subsequently, in a similar 2 input fashon.
