Arc Four Execution Unit
This chapter explains how to program the AFEU (Arc Four Execution Unit) to encrypt or
decrypt a message.
5.1 Arc Four Execution Unit Registers
All operational registers within the main control block are 32-bit addressable. However,
they may contain less than 32 bits.
Table 5-1 lists AFEU registers. These registers are described in more detail in the following
sections.
