6. PROM Option Bit Map
The initial value of each bit is “1”.
Notes: Do not write 0 to the vacant bit.
The read value of the vacant bit is 1, unless 0 is written to it.
Write the same value as each option register to the 3-byte vacant address that follows above option
registers.
Example: In the case of 0FE4H, write the same value to 0FE5H, 0FE6H and 0FF7H.
This optional information is taken into the OTPROM while the oscillation is being reset. Therefore, if the
hardware state is initially shifted to standby state after the power supply is turned on, the optional information
will not be valid during the transition (in a state of the initial value 1).
After the hardware standby state is cleared, the oscillation starts and the optional information becomes
valid.
Note that if the hardware is shifted to the standby or stop state in the course of a normal operation
(oscillation), the contents of the optional register are valid since the option data has already been taken
into the OTPROM.
