Channel Resume Mode
Figure 11-4 illustrates the operation of a context restore for a “new” channel program
when Channel Resume Mode has been selected (see Page 11-26). The PC is loaded
from CR7[31:16], and the lower half of R7 is loaded from CR7[15:0]. The operating
priority of the channel is taken from CR6[31:24] and all of R6 is loaded from CR6.
