Instruction Descriptions
Index
The index instruction specifies the RAM control indexes (R00h to R39h). It sets the register number in the
range of 000000 to 111001 in binary form. However, R40h to R44h are disabled since they are test registers.

Figure 2 Status Read Instruction
Start Oscillation (R00h)
The start oscillation instruction restarts the oscillator from the halt state in the standby mode. After issuing
this instruction, wait at least 10 ms for oscillation to stabilize before issuing the next instruction. (See the
Standby Mode section.)
If this register is read forcibly, 8760H is read.
