SLEEP MODE FUNCTION

EASY MODE

Also under this mode, the SLEEP Mode may be activated when the SLEEP Pin is in High State;

otherwise, the Normal Mode applies.

MCU MODE

The Sleep Mode is activated when the SLEEP Pin is set to HIGH. At this point, the clock and the RAM

stops in order to reduce the circuit current. When the SLEEP Pin is set to LOW, there is normal

operation.

SYSTEM RESET

PT2396 features an auto-rest function. The reset time is approximately 120 msec and the delay time is

set at 147.5msec if MCU Mode is enabled.
