Examples
The interaction between SCC and the host during transmission and reception of I-frames
is illustrated in the following two figures. The flow control with RR/RNR of I-frames during
transmission/reception is illustrated in figure 66. Both, the sequence of the poll cycle
and protocol errors are shown in figure 67.
