The SM89S16R1 will exit the Power Down mode with a reset or by a RTC (Real Time Clock) interrupt or by an
external interrupts pin enabled as level detects.
1. An external reset can be used to exit the Power Down state. The high on RST pin terminates the Power Down mode,
and restarts the clock. The program execution will restart from 0000H.
2. An external interrupt pin and RTC interrupt can be used to exit the Power Down state when the external interrupt or
RTC interrupt actives and provided the corresponding interrupt is enabled, while the global enable (EA) bit is set and
the external input has been set to a level detect mode or RTC interrupt set. If these conditions are met, then the low
level on the external pin or RTC interrupt re-starts the oscillator. Then device executes the interrupt service routine for
the corresponding external interrupt or RTC interrupt. After the interrupt service routine is completed, the program
execution returns to the instruction after the one that put the device into Power Down mode and continues from there.
