CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Input Ports)
K00–K03, K10
Table 4.3.1 (b) Input port control bits (2)
Input port data (0E0H, 0E1H D0)
The input data of the input port pins can be read with these
registers.
When 1 is read: High level
When 0 is read: Low level
Writing: Invalid
The value read is 1 when the pin voltage of the five bits of
the input ports (K00–K03, K10) goes high (VDD), and 0 when
the voltage goes low (VSS). These bits are reading, so writing
cannot be done.
