RESET:
The versatility of the MIOS1 timer architecture is based on multiple counters and cap-
ture/compare channel units interconnected on 16-bit counter buses. This section in-
cludes some typical application examples to show how the submodules can be
interconnected to form timing functions. The diagrams used to illustrate these exam-
ples show only the blocks utilized for that function.
To illustrate the timing range of the MIOS1 in different applications, many of the follow-
ing paragraphs include time intervals quoted in microseconds and seconds. The as-
sumptions used are that f
cycle) and with the maximum overall prescaling (32 µs cycle). For other f
cle rates and prescaler choices, the times mentioned in these paragraphs scale appro-
priately.
To measure the width of an input pulse, the MIOS double action submodule (MDASM)
has two capture registers so that only one interrupt is needed after the second edge.
The software can read both edge samples and subtract them to get the pulse width.
The leading edge sample is double latched so that the software has the time of one
full period of the input signal to read the samples to be sure that nothing is lost. De-
pending on the prescaler divide ratio, pulse width from 50 ns to 6.7 s can be mea-
sured. Note that a software option is provided to also generate an interrupt after the
first edge.
