1.2.4
S12XS Family power and ground pins are described below.
Because fast signal transitions place high, short-duration current demands on the power supply, use bypass
capacitors with high-frequency characteristics and place them as close to the MCU as possible.
1.2.4.1
External power and ground for I/O drivers. Bypass requirements depend on how heavily the MCU pins are
loaded. All V
1.2.4.2
Power supply input to the internal voltage regulator.
