CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Input Ports)
4.5 Input Ports (K00–K03 and K10–K13)
4.5.1 Configuration of input ports
The S1C63653 has eight bits of general-purpose input ports (K00–K03, K10–K13). Each input port termi-
nal provides an internal pull-down resistor that can be enabled by mask option.
Figure 4.5.1.1 shows the configuration of input port.

Fig. 4.5.1.1 Configuration of input port
Selection of "With pull-down resistor" with the mask option suits input from the push switch, key matrix,
and so forth. When "Gate direct" is selected, the port can be used for slide switch input and interfacing
with other LSIs.
The K13 port can also be used as the event counter input for the programmable timer.
4.5.2 Interrupt function
All eight bits of the input ports (K00–K03, K10–K13) provide the interrupt function. The conditions for
issuing an interrupt can be set by the software. Further, whether to mask the interrupt function can be
selected by the software.
Figure 4.5.2.1 shows the configuration of K00–K03 (K10–K13) interrupt circuit.
