1.3 RESET
The ZIC2410 should be reset to be operated. There are three kinds of reset sources. The first
one is to use an external reset pin (RESET#). When applying a low signal to this pin for more
than 1ms, ZIC2410 is reset. Second, ZIC2410 can be reset by an internal POR when it is
powered up as using the internal Power-On-Reset (POR) block. Third, as a reset by the
watchdog timer, a reset signal is generated when the internal counter of watchdog timer
reaches a pre-set value.
NOTE
Reference circuit of ZIC2410 is as follows. When the ZIC2410 is operated below minimum
operating voltage, a reset error will occur because of the unstable voltage. It is recommended
to use an external reset IC to improve stability in low voltage conditions.
