Power-On Reset
Each device in the Z8 Encore! XP F0823 Series contains an internal POR circuit. The
POR circuit monitors the supply voltage and holds the device in the Reset state until the
supply voltage reaches a safe operating level. After the supply voltage exceeds the POR
voltage threshold (V
timed out. If the crystal oscillator is enabled by the option bits, this time-out is longer.
After the Z8 Encore! XP F0823 Series device exits the POR state, the eZ8 CPU fetches the
Reset vector. Following the POR, the POR status bit in Watchdog Timer Control
(WDTCTL) register is set to 1.
