When the P3 node auto-assignment flag is set, the driver changes the mode to assign the
node number of the read request for each channel number automatically. See
Section 4.4 on page 79 for more information about node auto-assignment. For details
of the ICP starting address, see the ICP2432 Hardware Description and Theory of Oper-
ation.
