DI
Motorola/Intel/Codec Enable Select Input.
Host Mode:
When Low, the host interface is configured for Motorola
microcontrollers. When High, the host interface is configured for Intel
microcontrollers.
Hardware Mode:
Determines the line encode/decode selection when in unipolar mode.
When Low, B8ZS/HDB3 encoders/decoders are enabled for T1/E1
respectively. When High, enables AMI encoder/decoder (transparent
mode).
