5) IC1 (GATE ARRAY) DPITS Interface
DPITS Layer 1 interface. DR [1:0] is receiving input and DX [1:0] is transmitting output.
Layer 1 is the transmission method of Ping-Pong type which is AMI encoded. "SYNC/MAMC/D/B1/B2/P" data is
received in the first half at 125us/frame. After 1 bit time has passed since receiving P data, "SYNC/MAM/C/D/B1/B2/P"
is transmitted. 1 bit time is 512kHz. 7-bit time idle term comes after receiving P data.
