The I/O ports described as “Unused” in the tables above must be configured as
general purpose outputs (the logical level does not matter) in order to avoid their
electrical level to float.

CPM TDM Busses

The CPM in the MPC8260 features two Serial Interfaces, each one featuring four TDM
busses, for a total of eight TDM busses (TDMa1 ... TDMd1, and TDMa2 ... TDMd2). For
all the TDM busses used, clock and frame are common for receive and transmit directions
(configured in the SIxxMR registers).
