The I
and 300 ns. The I
shown in table 15-6. However, because of the rise and fall times, the I
specifications may not be satisfied at the maximum transfer rate. Table 15-8 shows output
timing calculations for different operating frequencies, including the worst-case influence of
rise and fall times.
t
(a) to provide coding to secure the necessary interval (approximately 1 µs) between issuance of
a stop condition and issuance of a start condition, or (b) to select devices whose input timing
permits this output timing for use as slave devices connected to the I
t
specifications for worst-case calculations of t
investigated include (a) adjusting the rise and fall times by means of a pull-up resistor and
capacitive load, (b) reducing the transfer rate to meet the specifications, or (c) selecting devices
whose input timing permits this output timing for use as slave devices connected to the I
bus.
