Packed TDM4 Mode
A special TDM mode is available that allows four channels to be
fit into a space of 64 bit clock cycles. This mode is called packed
TDM4 mode, or MOST™ mode. MOST (Media Oriented Systems
Transport) is a networking standard intended for interconnecting
multimedia components in automobiles and other vehicles. Many
ICs intended to interface with a MOST bus use a packed TDM4
data format.
