CHAPTER 3: PERIPHERAL CIRCUITS (Input Ports)
The S1C60N01 has one 4-bit input port (K00–K03). Input
port data can be read as a 4-bit unit (K00–K03).
The state of the input ports can be obtained by reading the
data (bits D3, D2, D1, D0) of address 0E0H. The input ports
can be used to send an interrupt request to the CPU via the
input interrupt condition flag. See Section 3.8 "Interrupt
and Halt", for details.
