Channel current descriptor pointer
ADDR | Address of current descriptor. When this field is ‘0’, there is no valid descriptor. Note: HW updates the current descriptor pointer CH_CURR_PTR with DESCR_NEXT_PTR after execution of the current descriptor. Note: Typically, when SW updates the current descriptor pointer CH_CURR_PTR, it also sets CH_IDX.X_IDX and CH_IDX.Y_IDX to ‘0’. |
