Modular Input/Output Subsystem (MIOS14)
17.12.6.2 MIOS14 Interrupt Level Register 1 (MIOS14LVL1)
This register contains the interrupt level that applies to the submodules number 15 to zero.
17.13 MIOS14 Function Examples
The versatility of the MIOS14 timer architecture is based on multiple counters and capture/compare
channel units interconnected on 16-bit counter buses. This section includes some typical application
examples to show how the submodules can be interconnected to form timing functions. The diagrams used
to illustrate these examples show only the blocks utilized for that function.
To illustrate the timing range of the MIOS14 in different applications, many of the following paragraphs
include time intervals quoted in microseconds and seconds. The assumptions used are that f
MHz with minimum overall prescaling (50 ns cycle) and with the maximum overall prescaling (32 µs
cycle). For other f
scale appropriately.
17.13.1 MIOS14 Input Double Edge Pulse Width Measurement
To measure the width of an input pulse, the MIOS14 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
