REST remains at high level. Elcodis is a trademark of Elcodis Company Ltd. When this bit is yt1381 to logic 0, the clock will start. The read or write operating flowcharts are shown on the next page. Then, choose either single mode or burst mode to input the data.

Functional operation of this device at other conditions beyond those listed in the specification is not implied and adtasheet exposure to extreme conditions may affect device reliability.

The data transfer is illustrated on the next page. There are eight registers used to control the month data, etc. Data can be de- livered 1 byte at a time burst bytes Then, choose either single mode or burst mode to input the data The number dagasheet days in each month and leap years are automatically adjusted.

For the most up-to-date information, please visit our web site at http: For data input, the data must be read after the rising edge of SCLK. Data inputs are entered starting with bit 0.

Taipei Office 5F, No. In order to minimize. Stresses exceeding the range specified under?

The test mode is used by Holtek only for testing purposes.

The value of the capacity depends on how accurate the crystal is. The REST pin must be taken low again after the transfer operation is completed.

Pad Description Pad No. Only three wires are required: The REST pin is also used to terminate either single-byte or burst mode data format. These bits control the operation of the oscillator and so data can be written to the register array. The value of the capacity depends on how accurate the crystal is.

Data can be de. All other trademarks are the property of their respective owners. This is to determine whether a read, write, or test cycle is operated and whether a single byte or burst mode transfer is to occur. The Write Protect bit cannot be written to in the burst mode. For the most up-to-date information, please visit our web site at http: When it is set as? The data bit outputs on the falling edge of the next eight SCLK cycles. The value of the capacity depends on how accurate the crystal is These are stress ratings only.
