PCF85263A

Tiny RTC with alarm, battery switch-over, and I2C-bus

INTA was configured to generate an interrupt when TSR2 loads a new time, hence an

interrupt pulse is seen on INTA.

• At t5, SW1 is opened. No action is taken by the IC.

• At t6, SW1 is open. The internal pull-up is active and the TS pin raises to vdd_int

level. The HIGH level is sampled and causes the stop signal to be released and time

starts counting again.
