Test Functions
For test purposes, the TEST pad is open. With a high resistance probe (R
C
20 pF), a test frequency f
TEST
of 128 Hz can be measured at the TEST pad. Connecting
TEST (for at least 32 ms) to V
DD
changes the motor period from the selected value to T
MT
(mask-selectable) while the pulse width remains unaffected. This feature can be used for test-
ing the mechanical parts of the clock.

Absolute Maximum Ratings
Absolute maximum ratings define parameter limits which, if exceeded, may permanently change or damage the device.
All inputs and outputs on Atmel’s circuits are protected against electrostatic discharges. However, precautions to minimize
the build-up of electrostatic charges during handling are recommended.
The circuit is protected against supply voltage reversal for typically 5 minutes.
