Table 7 depicts how these three modes are defined. All the information and explanations of the Products in this website is only for your reference. The actual specifications and applied technology will be based on each confirmed order. The WDTE bit can be read and written.

One security register to prevent intrusion of OTP memory codes? Set to “1” if the result of an arithmetic or logic operation is zero.

Without prescaler, the WDT time-out period is approximately 18 ms1 default. If they cannot be kept in this range, the frequency is easily affected by noise, This specification is subject to change without prior notice. Writable and readable as any other registers.

Enable the wake-up function. Output terminal for crystal oscillator or external clock input pin. A, it is recommended that R should not be greater than 40 K. Based on the above reasons, it must be kept in mind that all of the supply voltage, the ddatasheet temperature, the components of the RC oscillator, the package types, the way the PCB is layout, will affect the system frequency.


The device characteristic illustrated herein are not guaranteed for it accuracy. Upon power on, the upper 2 bits of Em78pp447sap-g are cleared.


ELAN owns the intellectual property rights, concepts, ideas, inventions, know-how whether patentable or not related to the Information and Technology herein after referred as ” Information and Technology” mentioned above, and all its related industrial property rights throughout the world, as now may exist or to be created in the future.

Check Table 6 2. ELAN reserves the right to modify the information without prior notification. Normally, all instructions are executed within one single instruction cycle one instruction consists of 2 oscillator periodsunless the program counter is changed by instruction “MOV R2,A”, “ADD R2,A”, or by datsaheet of arithmetic or logic operation on R2 e.

Clearing ROC will disable the R-option function. The ROC bit can be read and written.

The specifications of the Product and its applied technology will be updated or changed time by time. The oscillator is disabled oscillator is stopped, and the controller enters into SLEEP2 mode on the high-to-low transition and is enabled controller em78p447sap-t awakened from SLEEP2 mode on low-to-high transition. If for some reasons, the specification of the instruction cycle is not suitable for certain applications, try modifying the instruction as follows: If this pin remains at logic low, em78p47sap-g controller will also remain in reset condition.

Table 6 shows the events that may affect the status of T and Em78pp447sap-g. These can be pulled-high internally by software control.


In some graphic, the data maybe out of the specified warranted operating range. There is input status change wake-up function on Port 6, P74, and P Individual interrupt is enabled by setting its associated control bit in the IOCF to “1”.

Upon waking, the controller will continue to execute the succeeding address. Crystal input terminal or external clock input pin.


em78p447sap–g Measured on DIP packages. The WDT operation to be enabled or disabled should be appropriately controlled by software after waking up. Dubendorfstrasse 4, Zurich, Switzerland Telephone: Table 9 provides the recommended values of C1 and C2.

IOCF is the interrupt mask register. The entire risk as to the quality and performance of the application is with the user. If this pin remains at logic low, the controller will keep in reset condition. CONT register is both readable and writable. In addition, the instruction set has the following features: Input is driven at 2. When one of the interrupts enabled occurs, the next instruction will be fetched from address H.

The pulse width time constant should be kept long enough for Vdd to reached minimum operation voltage. The Watchdog timer and prescaler are cleared. A serial resistor may be necessary for AT strip cut crystal or low frequency mode.
