SN8P1600
8-bit micro-controller
6POWER ON RESET
OVERVIEW
SN8P1600 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 the following.
