x0FLGb Output. The FLGb output in axis-0. The FLGb

output is configured by MCR1 to function as either Sign

or Up/Down count direction indicator.

When configured as Sign, the FLGb output remains high

when CNTR is in an underflow state (caused by down

counts at or below zero), indicating a negative number.

When the CNTR counts up past zero, FLGb switches low,

indicating a positive number.

When configured as Up/Down indicatior, a high at the

FLGb indicates that the current count direction is up (in-

cremental) whereas a low indicates that the direction is

down or decremental.

The FLGb output can be disabled to remain at a fixed

logic high.

x1FLGb Output. The FLGb output of axis-1.

Functionally, it is identical with the FLGb output of axis-0.

x0CKO Output. Axis-0 count clock output. In non-

quadrature mode, the CKO output is identical with the in-

put-A clock. In quadrature mode, CKO is derived from the

filtered and decoded quadrature clocks applied at the A and

B inputs. In either mode CKO is a true representative of the

internal count clock.

x1CKO Output. Axis-1 count clock output.

Functionally, it is identical with the CKO output of axis-0.

VDD. Supply voltage. Positive terminal.

GND. Supply voltage. Negative terminal.
