JCHG | Injected channel group selection JCHG[y]=0: channel y is not part of the injected group JCHG[y]=1: channel y is part of the injected group If JSCAN=1, each of the selected channels is converted, one after another. The lowest channel (channel 0, if selected) is converted first and the sequence ends at the highest selected channel. If JSCAN=0, then only one channel is converted from the selected channels, and the channel selection is moved to the next channel. Writing JCHG, if JSCAN=0, resets the channel selection to the lowest selected channel. At least one channel must always be selected for the injected group. Writes causing all JCHG bits to be zero are ignored. |
