24-BIT x 4-AXES QUADRATURE COUNTER
FEATURES:
Read/write registers for count and I/O modes.
Count modes include: non-quadrature (Up/Down), Quadrature
(x1, x2, x4), Free-run, Non-recycle, Modulo-n and Range limit
Separate mode-control registers for each axis
Interrupt output and interrupt mask register
40 MHz count frequency, 5V
20 MHz count frequency, 3V
Sets of 24-bit counters, preset registers, comparators and
output latches and 8-bit status registers for each axis
Digital filtering of the input quadrature clocks for
noise immumity.
3-state Octal I/O bus
3V to 5.5V operating voltage range

GENERAL DESCRIPTION:
The LS7566R consists of four identical modules of 24-bit pro-
grammable counters with direct interface to incremental encod-
ers. The modules can be configured to operate as quadrature-
clock counters or non-quadrature up/down counters. In both
quadrature and non-quadrature modes, the modules can be fur-
ther configured into free-running, non-recycle, modulo-n and
range-limit count modes. The mode configuration is made
through two 8-bit read/write addressable control registers, MDR0
and MDR1. Data can be ported to a 24-bit preset register PR, or-
ganized in directly addressable (write-only) byte0 [PR0], byte1
[PR1] and byte2 [PR2] segments. PR can be transferred to the
24-bit counter CNTR, either by instruction to MDR1 or by hard-
ware input control. A 24-bit digital comparator perpetually checks
for the equality of the CNTR and the PR and can be used to set
an output flag when the equality occurs. For reading the CNTR,
its instantaneous value can be transferred to a 24-bit output latch
OL, either by instruction to MDR1 or by hardware input control.
The OL in turn can be read in directly addressable (read-only)
byte0 [OL0], byte1 [OL1] and byte2 [OL2] segments. An address-
able (read-only) Octal status register STR, stores the count re-
lated status information such as CNTR overflow, underflow,
count direction, etc. Data communication for read/write is per-
formed through an Octal 3-state parallel I/O bus
.
REGISTER DESCRIPTION:
Following is a list of the hardware registers. There are four
sets of registers, with name prefixes x0 through x3 to refer
to axes x0 through x3.
The information included herein is believed to be
accurate and reliable. However, LSI Computer Systems,
Inc. assumes no responsibilities for inaccuracies, nor for
any infringements of patent rights of others which may
result from its use.
