| 21 | Temperature Compensated Crystal (Xtal) Oscillator (TCXO) and a 32.768 kHz quartz |
| 22 | crystal optimized for very high accuracy and very low power consumption. The PCF2127 |
| 23 | has a selectable I2C-bus or SPI-bus, a backup battery switch-over circuit, a |
| 24 | programmable watchdog function, a timestamp function, and many other features. |
