HD66773R
Instructions
The following are detail explanations of instructions with illustrations of instruction bits (IB15-0) assigned
to each interface.
Index
The index instruction specifies a index (R00h to R3Bh) of control registers and RAM control, that is
accessed. It sets the register number from 0000000 to 11111111 in binary form. Do not try to access to the
register to which instruction is not assigned.

Status Read
The status read instruction reads the internal status of the HD66773R.

Start Oscillation (R00h)
The start oscillation instruction restarts the oscillator in a halt state during standby mode. After executing
this instruction, wait at least 10 ms for stabilizing oscillation before issuing a next instruction. For details,
see the “Standby Mode” section.
“0773”H is read out, if this register is forced to read out.
