CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Input Ports)
4.4.3 Mask option
The contents that can be selected with the input port mask option are as follows:
(1) Internal pull-down resistor can be selected for each of the nine bits of the input ports (K00–K03, K10,
K20–K23).
When you have selected "Gate direct", take care that the floating status does not occur for the input.
Select "With pull-down resistor" for input ports that are not being used.
(2) The input interrupt circuit contains a noise rejector for preventing interrupt occurring through noise.
The mask option enables selection of whether to use the noise rejector for each separate terminal
series.
When "Use" is selected, a maximum delay of 1 msec occurs from the time interrupt condition is
established until the interrupt factor flag (IK) is set to "1".
4.4.4 Control of input ports
Table 4.4.4.1 lists the input ports control bits and their addresses.
