Product data sheet Rev. 4.1 — 27 November 2015 29 of 100 NXP Semiconductors PCF85263A Tiny RTC with alarm, battery switch-over, and I2C-bus Timestamps work in both RTC and stop-watch mode. During battery operation, the mechanical switch detector may also be used to trigger the timestamp. The timestamp registers are read only and cannot be written. It is possible to set all three registers to 0 with the CTS instruction in the Resets register (Section 8.15 on page 58). The mode for each register is controlled by the TSR_mode register. Fig 16.
