ASIC
IC101 and IC503(ASIC) are connected by an I2C communication.
EHS terminals are controlled by IC503 (ASIC).
EHS terminals are controlled by IC503 (ASIC).
*This ASIC supports Plantronics and Jabra EHS.
Plantronics control signals : PSB IN/OUT
Jabra control signals : JABRA_UTX/URX
Jabra control signals : JABRA_UTX/URX
The audio signals are exchanged with IC101 through HEADSET JACK.
