Message Digest Execution Unit
This chapter explains how to program the MDEU (Message Digest Execution Unit) within
the MPC180 to hash a message for authentication.
6.1 Operational Registers
All operational registers within the MDEU are 32-bit addressable, however they may
contain less than 32 bits.
Table 6-1 lists message registers. These registers are described in more detail in the
following sections.
