Channel Restart Mode
Figure 11-5 illustrates the operation of a context restore for a “new” channel program
when Channel Restart Mode has been selected (see Page 11-25). The PC is loaded
with the channel entry table address, and the lower half of R7 is loaded from CR7[15:0].
The upper half of CR6 is discarded. The operating priority of the channel is taken from
CR6[31:24] and all of R6 is loaded from CR6.
