Reset Sources
Power-On Reset
Table 10 lists the possible sources of a system reset.
Each device in the Z8 Encore! F0830 Series contains an internal Power-On Reset circuit.
The POR circuit monitors the digital supply voltage and holds the device in the Reset state
until the digital supply voltage reaches a safe operating level. After the supply voltage
exceeds the POR voltage threshold (V
POR counter has timed out. If the crystal oscillator is enabled by the option bits, the time-
out is longer.
After the Z8 Encore! F0830 Series device exits the Power-On Reset state, the eZ8 CPU
fetches the reset vector. Following the Power-On Reset, the POR status bit in the Reset
Status (RSTSTAT) Register is set to 1.
Figure 6 displays the Power-On Reset operation. See the
on page 184 for the POR threshold voltage (V
