Actions
the input pins, it is possible that an internal input level may be generated due to noise, etc., hence
causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of
CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin
should be connected to VDD or GND with a resistor, if it is considered to have a possibility of being
an output pin. All handling related to the unused pins must be judged device by device and related
specifications governing the devices.
7.4 Status before Initialization of MOS Devices
Power-on does not necessarily define initial status of MOS device. Production process of MOS does
not define the initial operation status of the device. Immediately after the power source is turned ON,
the devices with reset function have not yet been initialized. Hence, power-on does not guarantee
out-pin levels, I/O settings or contents of registers. Device is not initialized until the reset signal is
received. Reset operation must be executed immediately after power-on for devices having reset
function.
