Noise
Input-only Pins
If different power supplies are provided to the system, as shown in Figure 1.213 Circuit example, and the voltage of an
unused input-only pin is higher than Vcc, do not directly connect the dedicated input pin to the power supply. As in the
circuit example indicated by the arrow, connect the input-only pin to the power supply via a resistor rated at approxi-
mately 1 kΩ. The above applies even if the power rise time is different at power-on.
If the voltage of the input pin voltage is higher than Vcc, latch up could occur.
*: A resistor is not required when using a Vcc voltage equal to or higher than the voltage of the dedicated input pin.
When HOLD input is used, set P4
microprocessor mode or memory expansion mode.
When A/D conversion is not carried out, select not to connect V
1. To carry out A/D conversion, start the conversion 1µs or longer after connecting V
In microprocessor mode, the SFR, internal RAM and external memory space can be accessed. Therefore, the
internal ROM area cannot be accessed.
If microprocessor mode is set (“H” is applied to the CNV
be accessed even if the CPU shifts to memory expansion mode or single-chip mode.
If the microprocessor is reset when “H” is applied to the CNVss pin, the internal ROM cannot be read.
Connect a bypass capacitor (at least 0.1 µF) using the shortest and thickest wire possible.
