R3F can be cleared by instruction, but cannot be set by instruction. See the configuration of the data memory in Fig.


Table 6 shows the events that may affect the status of T and P. The actual specifications and applied technology will be based on each confirmed order. The WDT can be enabled or disabled any time during normal mode by software programming. In some graphic, the data maybe out of the specified warranted operating range. Table 7 depicts how these three modes are defined.

Thus, the subroutine entry address can be located anywhere within a page. To avoid reset from occurring when the port6 status changed interrupt enters into interrupt vector or is used to wake-up the MCU, the WDT prescaler must be set above 1: Moreover, the frequency also changes slightly from one chip to another due to the manufacturing process variation.

During normal operation or sleep mode, a WDT time-out if enabled will cause the device to reset. ELAN represents no warranty for the use of the specifications described, either expressed or implied, including, but not limited, to the implied warranties of merchantability and fitness for particular purposes.


The WDT operation to be enabled or disabled should be appropriately controlled by software after waking up.

IOCB Register is both readable and writable. Thus, the computed jump is limited to the first locations of em78;447sap-g page. Set to “1” if the result of an arithmetic or logic operation is zero.

Two clocks per instruction cycle? The values of T and P listed in Table 5 below are used to verify the event that triggered the processor to wake up.

The WDT will keep on running even after the oscillator driver has been turned off i. Refer to the section on Instruction Set.

R0 Indirect Addressing Register R0 is not a physically implemented register. A serial resistor may be necessary for AT strip cut crystal or low frequency mode.

When an interrupt is generated by the INT instruction enabledthe next instruction will be fetched from address H. All the information and explanations of the Products in this website is only for your reference.


Crystal input terminal or external clock input pin. The diode D acts as a short circuit at the moment of power down. If for datasheey reasons, the specification of the instruction cycle is not suitable datazheet certain applications, try modifying the instruction as follows: The oscillator starts or is running? The device characteristic illustrated herein are not guaranteed for it accuracy.


The WDTE bit can be dstasheet and written. This condition may cause a poor power on reset.
