In this device, clearing the KBFSEL bit to 0 in KBCRH enables the KBF bit in KBCRL to be used
as a flag for the interrupt generated by the fall of KCLK input.
Figure 17.13 shows the setting method and an example of operation.
Note: * The KBF setting timing is the same as the timing of KBF setting and KCLK automatic I/O inhibit bit
