The TS monitors the junction temperature of the
PCF50603. It offers the following features:
The behaviour of the TS is shown in Figure 13.

A HIGHTMP interrupt is generated when the temperature
threshold is passed for more than 62 ms (debouncing
time). When a HIGHTMP interrupt is generated the host
controller should initiate a transition to STANDBY state.
In case the host controller does not initiate a transition to
the STANDBY state within 1 second after the interrupt
occurred, the OOC forces the PCF50603 to the STANDBY
state in order to prevent damage to the circuit.
The hysteresis and debounce time have been built in to
prevent fast cycling of the HIGHTMP signal.
