The digital noise filter section is responsible for
rejecting noise on the incoming quadrature signals.
Schmitt Trigger inputs and a three-clock cycle delay fil-
ter combine to reject low-level noise and large, short
duration noise spikes that typically occur in noise prone
applications, such as a motor system.
The filter ensures that the filtered output signal is not
permitted to change until a stable value has been
registered for three consecutive clock cycles.
For the QEA, QEB and INDX pins, the clock divide
frequency for the digital filter is programmed by bits
QECK<2:0> (DFLTCON<6:4>) and are derived from
the base instruction cycle T
To enable the filter output for channels QEA, QEB and
INDX, the QEOUT bit must be ‘1’. The filter network for
all channels is disabled on POR and BOR.
14.5
When the QEI module is not configured for the QEI
mode, QEIM<2:0> = 001, the module can be
configured as a simple 16-bit timer/counter. The setup
and control of the auxiliary timer is accomplished
through the QEICON SFR register. This timer functions
identically to Timer1. The QEA pin is used as the timer
clock input.
When configured as a timer, the POSCNT register
serves as the Timer Count register and the MAXCNT
register serves as the Period register. When a
Timer/Period register match occurs, the QEI interrupt
flag will be asserted.
The only exception between the general purpose
timers and this timer is the added feature of external
up/down input select. When the UPDN pin is asserted
high, the timer will increment up. When the UPDN pin
is asserted low, the timer will be decremented.
The UPDN control/Status bit (QEICON<11>) can be
used to select the count direction state of the Timer
register. When UPDN = 1, the timer will count up. When
UPDN = 0, the timer will count down.

Changing the operational mode (i.e., from
QEI to Timer or vice versa), will not affect

.
In addition, control bit, UDSRC (QEICON<0>),
determines whether the timer count direction state is
based on the logic state written into the UPDN
control/Status bit (QEICON<11>), or the QEB pin state.
When UDSRC = 1, the timer count direction is
controlled from the QEB pin. Likewise, when
UDSRC = 0, the timer count direction is controlled by
the UPDN bit.

14.6.1
The QEI module will be halted during the CPU Sleep
mode.
14.6.2
During CPU Sleep mode, the timer will not operate,
because the internal clocks are disabled.
14.7
Since the QEI module can function as a Quadrature
Encoder Interface, or as a 16-bit timer, the following
section describes operation of the module in both
modes.
14.7.1
When the CPU is placed in the Idle mode, the QEI
module
(QEICON<13>) = 0. This bit defaults to a logic ‘0’ upon
executing POR and BOR. For halting the QEI module
during the CPU Idle mode, QEISIDL should be set to ‘1’.
