Section 9 Bus State Controller (BSC)
When the WM bit in CSnWCR is cleared to 0, the external wait input WAIT signal is also
sampled. WAIT pin sampling is shown in figure 9.9. A 2-cycle wait is specified as a software
wait. The WAIT signal is sampled on the falling edge of CKIO at the transition from the T1 or Tw
cycle to the T2 cycle.
