Reset
The ASIC mounted on KX-TDA1180 activates the reset signal of KX-TDA1186 through the connector CN6-32pin.
The reset signal connects from ASIC to IC6,IC7,IC508 and IC609.
After releasing the reset signal, the ASIC initializes CODEC and CID-ASIC.

Local Highway Interface
Packs 2.048, 4.096, 8.192 MHz highway (Max.64 timeslot). (voice communication bus in the circuit board)
The PCM data of arbitrary streams 0~15 (128 timeslot / 1 stream) on the CT bus can switch to the arbitrary local highway (64
timeslot) by the local TSW.
The timeslot configuration example of the local highway is shown below.
Timeslots between slot 0 and slot 7 are used by KX-TDA1180 base board.
