16.2.2.1.1. Reset
On startup, releasing the ASIC reset is executed by EC_nRST through MPR.
After releasing the ASIC, the local reset signal should be sent to CODEC by releasing the soft rest from MPR, and CODEC fac-
tor should be downloaded from MPR.

16.2.2.2. 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 8 and slot 15 are reserved for KX-TDA1186 option card.
