When KBIOE is 0, the internal KCLK and internal KD settings are fixed at 1. Therefore, if the
KCLK pin is low when the KBIOE bit is set to 1, the edge detection circuit operates and the
KCLK falling edge is detected.
If the KBFSEL bit and KBE bit are both 0 at this time, the KBF bit is set. Figure 19.19 shows the
timing of KBIOE setting and KCLK falling edge detection.
