NOTES ON USAGE
Handling of Power Source Pins
In order to avoid a latch-up occurrence, connect a capacitor suit-
able for high frequencies as bypass capacitor between power
source pin (V
source pin (V
pin), and between program power source pin (CNVss/V
GND pin for flash memory version when on-board reprogramming
is executed. Besides, connect the capacitor to as close as pos-
sible. For bypass capacitor which should not be located too far
from the pins to be connected, a ceramic capacitor of 0.01 F–0.1
