The TOE bit enables the time-out detection function. When the TOE bit is set to "1", time-out is detected
and the I
The internal counter measures the time-out detection time and the TOSEL bit selects between two
modes, long time and short time. When time-out is detected, set the ES0 bit to "0" (I
disabled) and reset the counter.
The TOF flag indicates the time-out detection. If the internal counter which measures the time-out
period overflows, the TOF flag is set to “1” and the I
same time.
The TOSEL bit selects time-out detection period from long time mode and short time mode. When the
TOSEL bit is set to "0", long time mode is selected. When it is set to "1", short time mode is selected,
respectively. The internal counter increments as a 16-bit counter in long time mode, while the counter
increments as a 14-bit counter in short time mode, based on the I
source. Table 16.7 shows examples of time-out detection period.
The ICK4 to 2 bits, ICK1 and ICK0 bits in the S3D0 register, and the PCLK0 bit in the PCLKR register
select the system clock (V
The SCPIN bit monitors the stop condition detection interrupt. The SCPIN bit is set to “1” when the I
bus interface interrupt is generated by detecting the STOP condition. When this bit is set to "0" by pro-
gram, it becomes "0". However, no change occurs even if it is set to "1".
