31. Module: JTAG
At a Power-on Reset (POR), when JTAG is
disabled in the Configuration bits, the I/O pin with
TMS function produces an active-high logic pulse
with a pulse width in the order of milliseconds.

32. Module: QEI
The Velocity Counter (VELxCNT) is a 16-bit wide
register that increments or decrements based on
the signal from the quadrature decoder logic.
Reading this register results in a Counter Reset.
Typically, the user application should read the
Velocity Counter at a rate of 1-4 kHz.

Reading this register results in a Counter Reset.
Typically, the user application should read the
Velocity Counter at a rate of 1-4 kHz.
As a result of this issue, the Velocity Counter may
miss a count if the user application reads the
Velocity Counter register at the same time as a
(+1 or -1) count increment occurs.
