The extra external reset circuit will work well if Vdd can rise at very fast speed 50 ms or less. Refer datasbeet the section on Instruction Set.

Moreover, the frequency also changes slightly from one chip to another due to the manufacturing process variation. Bit 2 Z Zero flag. A, during sleep mode? The device vatasheet illustrated herein are not guaranteed for it accuracy.

Two clocks per instruction cycle? Individual interrupt is enabled by setting its associated control bit in the IOCF to “1”.

The ODE bit can be read and written. One security register to prevent datasheey of OTP memory codes? The most up-to-day information is available on the website http: The SLPC bit can be read and written. Instruction period option bit. Based on the above reasons, it must be kept in mind that all of the supply voltage, the operation temperature, the components of the RC oscillator, the package types, the way the PCB is layout, will affect the system frequency.


The T and P flags of R3 can be used rm78p447sap-g determine the source of the reset wake-up. The entire risk as to the quality and performance of the application is with the user.

The option bits cannot be accessed during normal program execution. R3F can be cleared by instruction, but cannot be set by instruction.

On the contrary, for very low Rext values, for instance, 1 K? One program page datzsheet words long. Set Port6 or P74 or P75 Input 2.

If for some reasons, the specification of the instruction cycle is not suitable for certain applications, try modifying the instruction as follows: In this case, the execution takes two instruction cycles.

Temperature This specification is subject to change without prior notice. Without prescaler, the WDT time-out period is approximately 18 ms1 default. In order to ensure the stable output of the oscillator, once the oscillator is enabled again, there is a delay for approximately 18ms1 oscillator start-up timer, OST before the next instruction of the program is executed.


Timing m easurements are made at 2. VDD, Prescaler Set to 1: A, it is recommended that R should not be greater than 40 K. There is input status change wake-up function on Port 6, P74, and P While entering sleep mode, WDT if enabled is cleared but keeps on running.

Upon waking, the controller will continue to execute the succeeding address. Watchdog timer enable bit.

If this pin remains at logic low, the controller will keep in reset condition. The watchdog timer is a free running on-chip RC oscillator.

VDD to 5V R: If they cannot be kept in this range, the frequency is easily affected by noise, This specification is subject to change without prior notice.

Previous status before reset This specification is subject to change without prior notice. These can be pulled -high internally by software control.
