Outline of commands

When the MPU accesses the M66307 for write with C/D =

High as shown in Table 1, the M66307 reads the information

on the data bus into the register as a command. When the MPU

accesses the M66307 for write with C/D = Low, the M66307 reads

the information into the internal memory as data. There are eight

kinds of commands classified by the upper four bit (D15 to D12).
