4 / 6 page NJU6355 - 4 - 3. Timer Data Writing When both of the I/O terminal and the CE terminal are "H", update is stopped, the oscillator divider is cleared, and the timer data can be written to the NJU6355. The timer data is written into the shift register from the DATA terminal by synchronized with rising edge of the clock signal input from the CLK terminal, and the data is transferred from the shift register to the timer counter by synchronized with falling edge of the CE signal. In this time the second-counter is cleared to "0", and the oscillator divider start the operation. The input data strings are LSB first of each digit as shown below. Type E Year Month Day Days of Week Hour Minute Second The data is read out from LSB of Year, and last 44-bit is effective. < Write Down Timing > 4. Low Voltage Detector The NJU6355 series incorporate the low battery detector. If the supply voltage reduce to the detection level, (EE)H is written into each digit of the shift register as warning code for the CPU. 5. Data Access The NJU6355 series can operate from 2.0V to 5.5V. However, it is not allow the data access out of the range of 5V±10%. It may be broken the data unless 5V±10%. Thus, when the data access, the CE terminal should be "H" after the power supply rise to 5V±10%, then start the operation. CLK CE I/O The data is input into the shift register at rising edge of the CLK. The data in the shift register is transferred to the timer counter at this falling edge of the CE, then the oscillator divider start the operation. Year 1 2 3 4 5 6 7 3 4 5 6 7 0 1 2 3 4 5 6 7 0 3 4 5 6 7 Minute Data Input Shift Register Note) When the CE signal is which rising edge or falling edge, the CLK signal should be fixed to "L". And so, before the CE signal is raised, the I/O signal should be fixed to "H". |
