Since each resonator has dagasheet own attribute, user should refer to its specification for appropriate values of C1 and C2. The oscillator is disabled oscillator is stopped, and the controller enters into SLEEP2 mode on the high-to-low transition and is enabled controller is awakened from SLEEP2 mode on low-to-high transition.

It cannot be addressed. Set Port6 or P74 or P75 Input 2. Bit 2 Z Zero flag. Table 7 depicts how these three modes are defined.

A, during sleep mode? Once in the interrupt service routine, the source of an interrupt can be determined by polling the flag bits in R3F. VDD to 5V R: IOCF register is both readable and writable. Previous status before reset This specification is subject to change without prior notice. The ODE bit can be read and written. IOCB Register is both readable and writable. For design reference only. Table 9 provides the recommended values of C1 and C2.

SLPC is used to control the oscillator operation. Input is driven at 2. Individual interrupt is enabled by setting its associated control bit in the IOCF to “1”. There is input status change wake-up function on Port 6, P74, and P A serial resistor may be necessary for AT strip cut crystal or low frequency mode. This condition may cause a poor power on reset. The Watchdog timer and prescaler are cleared. Dubendorfstrasse 4, Zurich, Switzerland Telephone: Otherwise, the R-option function is introduced.

R0 Indirect Addressing Register R0 is not a physically implemented register. Bit 3 PAB Prescaler assignment bit. Thus, the subroutine entry address can be located anywhere within a page. Bit 4 T Darasheet bit.

Set as TCC overflows; flag cleared by software. The T and P flags of R3 can be used to determine the source of the reset wake-up. Zhangjiang, Hi-tech Park, Shanghai Telephone: VDD, Prescaler Set to 1: The WDTE bit can be read em78p447sapg written. XTAL2 type low frequency, Clearing ROC will disable the R-option function.

A mA mA This specification is subject to change without prior notice. CONT register is both readable and writable. If this pin remains at logic low, the controller will also remain in reset condition. The oscillator starts or is running? When an interrupt is generated by the INT instruction enabledthe next instruction will be fetched from address H.

Programmable free running watchdog timer? Temperature This specification is subject to change without prior notice. RC oscillator input pin.

Moreover, the frequency also changes slightly from one chip to another due to the manufacturing process variation. The diode D acts as a short circuit at the moment of power down.

The pulse width time constant should be kept long enough for Vdd to reached minimum operation voltage. The entire risk as to the quality and performance of the application is with the user. All the information and explanations of the Products in this website is only for your reference.

This way, the EM78PS will reset and work normally.
