Notes 1.
The values for on-chip pull-down resistors (R
30
and R
31
) and on-chip mask-option pull-down resistors
(R
40
and R

) can be selected according to the following conditions.

Notes 1.
The mixed use of resistor values is not possible for both on-chip pull-down resistors and
on-chip mask-option pull-down resistors.
2.
The resistor value selected for all of pins FIP0 to FIP15 is connected as an on-chip pull-
down resistor regardless of the use of the option resistor.
3.
The use of the option resistor of the on-chip mask-option pull-down resistor can be specified
in 1-bit units. The selected resistor value is connected to bits for which the use of the option
resistor is specified.

Remark
Unless otherwise specified, the characteristics of alternate-function pins are the same as those of port
pins.
