UNUSED PORTS

All unused ports should be set properly that current

flow through the port does not exist.

First conseider the setting to input mode. Be sure that

there is no current flow after considering its relation-

ship with external circuit. In input mode, the pin im-

pedance viewing from external MCU is very high that

the current does not flow.

But input voltage level should be VSS or VDD. Be

careful that if unspecified voltage, i.e. if unfirmed

voltage level is applied to input pin, there can be little

current ( max. 1mA at around 2V) flow.

If it is not appropriate to set to input mode, then set to

output mode considering there is no current flow.

Setting to High or Low is decided considering its

relationship with external circuit. For example, if there

is external pull-up resistor then it is set to output mode,

i.e. to High, and if there is external pull-down register,

it is set to low.
