8.6.6 START Condition Generation Method
When the ESO bit of the I
2
C control register (address 00DA
16
) is “1,”
execute a write instruction to the I
2
C status register (address 00D9
16
)
to set the MST, TRX and BB bits to “1.” A START condition will then
be generated. After that, the bit counter becomes “000
2
” and an SCL
for 1 byte is output. The START condition generation timing and BB
bit set timing are different in the standard clock mode and the high-
speed clock mode. Refer to Figure 8.6.9 for the START condition
generation timing diagram, and Table 8.6.2 for the START condition/
STOP condition generation timing table.

8.6.7 STOP Condition Generation Method
When the ESO bit of the I
2
C control register (address 00DA
16
) is “1,”
execute a write instruction to the I
2
C status register (address 00D9
16
)
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 genera-
tion timing and the BB flag reset timing are different in the standard
clock mode and the high-speed clock mode. Refer to Figure 8.6.10
for the STOP condition generation timing diagram, and Table 8.6.2
for the START condition/STOP condition generation timing table.
