BB bit set timing are different in the standard clock mode and the high-speed clock mode. Refer to
Figure 2.11.42 for the START condition generation timing diagram, and Table 2.11.13 for the START

for setting the MST bit and the TRX bit to “1” and the BB bit to “0”. A STOP condition will then be
generated. The STOP condition generation timing and the BB flag reset timing are different in the
standard clock mode and the high-speed clock mode. Refer to Figure 2.11.43 for the STOP condition
generation timing diagram, and Table 2.11.13 for the START condition/STOP condition generation
timing table.
