M0:e.1 Bit 4 - Soft Reset (Dynamic)

The Soft Reset bit can be used to reset the counter in combination with
the physical reset signals. Setting this bit (to 1) resets the counter, via
the Reset Mode bits, if Soft Reset (bit 7) is selected. The 0 to 1 transition
of the Soft Reset condition (M0:e.1/5-7) resets the counter when
configured to do so (refer to Counter Reset Control in Chapter 2).

M0:e.1 Bits 5,6,7 - Reset Mode (Static)

These bits allow you to select the device(s) that reset the counter. Bit
5 enables the Z reset, Bit 6 enables the limit switch reset, and bit 7
enables the soft reset, as shown below:

IMPORTANT

The Soft Reset bit must be held at 1 until the counter
resets. The Reset Input bit (I:e.0/12) can be used to
detect a counter reset.
