Note: Previous versions of Motorola IDL-defined bit functions, called auxiliary (A) and
maintenance (M), were eliminated from the IDL definition when it was concluded
that the IDL control channel would be out-of-band. They were defined as a
subset of the Motorola SPI format called serial control port (SCP). If you prefer
to implement the A and M bit functions as originally defined, you can program the
time-slot assigner to access these bits and route them transparently to a serial
communication controller or serial management controller. To perform the
out-of-band signaling required, use the MPC823e serial peripheral interface.
