Figure 19.12 shows the receive timing.
19.4.8
If the KBS bit in KBCRH is set to 1 with other keyboard buffer control units in reception*, the
KCLK is automatically pulled down. Figure 19.13 shows receive timing and the KCLK.
Note: * Period from the first falling edge of KCLK to completion of reception (KBF = 1).
