Instruction bits
Instructions
The following are detail explanations of instructions with illustrations of instruction bits (IB15-0) assigned
to each interface.
Index
The index instruction specifies the index (R00h to R4Fh) of control register and RAM control. It sets the
register number from 0000000 to 1111111 in binary form. Do not try to access to the register to which the
index is not assigned.
