18.7.1
A power-on event will generate an internal POR pulse
when a V
at the POR circuit threshold voltage (V
nominally 1.85V. The device supply voltage character-
istics must meet specified starting voltage and rise rate
requirements. The POR pulse will reset a POR timer
and place the device in the Reset state. The POR also
selects the device clock source identified by the
oscillator configuration fuses.
