PCF2131-ARD evaluation board
The next tab is Alarm . The interface of this tab is shown in Figure 18 . From here the
alarm corresponding registers can be managed. See the PCF2131 datasheet to see
more details regarding the alarm function and register map of the DUT IC. Note that
for each command / button the register address is displayed on the interface, so that
the user can easily identify the register function in the register map, described in the
PCF2131 datasheet.

The following tabs are listed below:
• Timestamp: Figure 19 . See the datasheet for more details regarding timestamp
functions of PCF2131 RTC.
• Watchdog Timer: Figure 20 . See the datasheet for more details regarding watchdog
timer.
• Interrupt Mask: Figure 21 . On the upper blue region, right side, two indicators are
monitoring in real-time the state of the INTA / INTB interrupts of the DUT IC. Note that,
checking all boxes means the interrupts are fully masked, INTA / INTB are not active.
• PWR/BATT:
Figure 22 . See the datasheet for more details regarding power
management of the PCF2131 RTC.
