K00–K03, K10: Input port data (2E3H, 2E7HD0)
Input data of the input port terminals can be read out with these registers.
When "1" is read out : High level
When "0" is read out : Low level
Writing : Invalid
The read-out is "1" when the terminal 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 dedicated for read-out, so writing cannot be done.
KCP00–KCP03, KCP10: Input comparison registers (2E4H, 2E7HD1)
Interrupt conditions for terminals K00–K03 and K10 can be set with these registers.
When "1" is written : Falling edge
When "0" is written : Rising edge
Read-out : Valid
The interrupt conditions can be set for the rising or falling edge of input for each of the five bits (K00–K03
and K10), through the input comparison registers (KCP00–KCP03 and KCP10).
At initial reset, these registers are set to "0".
EIK00–EIK03, EIK10: Interrupt mask registers (2E5H, 2E7HD2)
Masking the interrupt of the input port terminals can be selected with these registers.
When "1" is written : Enable
When "0" is written : Mask
Read-out : Valid
With these registers, masking of the input port bits can be selected for each of the five bits.
Writing to the interrupt mask registers can be done only in the DI status (interrupt flag = "0").
At initial reset, these registers are all set to "0".
