... Functional description The PCA8565 contains sixteen 8-bit registers with an auto-incrementing address register, an on-chip 32.768 kHz oscillator with one integrated capacitor, a frequency divider which provides the source clock for the Real Time Clock/calender (RTC), a programmable clock output, a timer, an alarm, a voltage-low detector and a 400 kHz ...

... CLKOUT is an open-drain output and enabled at power-on. If disabled it becomes high-impedance. 8.4 Reset The PCA8565 includes an internal reset circuit which is active whenever the oscillator is stopped. In the reset state the I the address pointer, are cleared with the exception of bits FE, VL, TD1, TD0, TESTC and AE which are set to logic 1. ...

... The addressing is always carried out with the first byte transmitted after the start procedure. The PCA8565 acts as a slave receiver or slave transmitter. Therefore the clock signal SCL is only an input signal, but the data signal SDA is a bidirectional line. The PCA8565 slave address is shown in Fig 10 ...
