measurement. The software designates whether the rising or falling edge of the input signal is to be used
for the measurements. When the edge is detected, the state of the 16-bit counter bus is stored in register A
and the content of register B1 is transferred to register B2. After register B2 is safely latched, the content
of register A is transferred to register B1. This procedure gives the software coherent current and previous
samples in registers A and B2 at all times. An interrupt is available for the cases where the software needs
to be aware of each new sample. Note that a software option is provided to also generate an interrupt after
the first edge.
17.13.3 MIOS14 Double Edge Single Output Pulse Generation
Software can initialize the MIOS14 to generate both the rising and the falling edge of an output pulse. With
a MDASM, pulses as narrow as 50 ns can be generated since software action is not needed between the
edges. Pulses as long as 2.1 s can be generated. When an interrupt is desired, it can be selected to occur on
every edge or only after the second edge.

single output pulse. The software puts the compare value for one edge in register A and the other one in
register B2. The MDASM automatically creates both edges and the pulse can be selected by software to
be a high-going or a low-going. After the trailing edge, the MDASM stops to await further commands from
the software. Note that a single edge output can be generated by writing to only one register.
