MITSUBISHI MICROCOMPUTERS
M37274EFSP
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER with CLOSED CAPTION DECODER
and ON-SCREEN DISPLAY CONTROLLER
PRELIMINARY
Notice: This is not a final specification.
Some paramentic limits are subject to change.
(9) START/STOP Condition Detect Conditions
The START/STOP condition detect conditions are shown in Figure
52 and Table 9. Only when the 3 conditions of Table 9 are satisfied,
a START/STOP condition can be detected.
Note:
When a STOP condition is detected in the slave mode
(MST = 0), an interrupt request signal “IICIRQ” is generated
to the CPU.
(8) STOP Condition Generation Method
When the ES0 bit of the I
2
C control register (address 00F9
16
) is “1,”
execute a write instruction to the I
2
C status register (address 00F8
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 51 for
the STOP condition generation timing diagram, and Table 8 for the
START condition/STOP condition generation timing table.
