SN8P1700
8-bit micro-controller build-in 12-bit ADC
6POWER ON RESET
OVERVIEW
SN8P1700 provides two system resets. One is external reset and the other is low voltage detector (LVD). The external
reset is a simple RC circuit connecting to the reset pin. The low voltage detector (LVD) is built in internal circuit. When
one of the reset devices occurs, the system will reset and the system registers become initial value. The timing
diagram is as following.
