Capacitive Loads
The capacitive loads are specified in
. Ceramic capacitors with X7R dielectricum are required.
A.5.3
Chip Power-up and Voltage Drops
LVI (low voltage interrupt), POR (power-on reset) and LVRs (low voltage reset) handle chip power-up or
drops of the supply voltage. Their function is shown in
