IR. The IR is an 8-bit register that fetches instruction bytes from
the received data stream and executes them to perform such
functions as setting up the operating mode for the chip (load the
MDR) and data transfer among the various registers.

CNTR. The CNTR is a software configurable 8, 16, 24 or 32-bit up/down counter which counts the up/down pulses resulting from
the quadrature clocks applied at the A and B inputs, or alternatively, in non-quadrature mode, pulses applied at the A input. By
means of IR intructions the CNTR can be cleared, loaded from the DTR or in turn, can be transferred into the OTR. The “clear CNTR”
and the “load CNTR” commands in the ”range-limit” mode, however have limitations. In this mode when the CNTR is frozen in up count
direction at CNTR = DTR, a “clear CNTR” command will only function if the count direction is reversed from up to down. Similarly,
in the down direction at CNTR = 0, a “load CNTR” command will only function if the direction is reversed from down to up.
OTR.
The OTR is a software configuration 8, 16, 24 or 32-bit register which can be read back on the MISO output.
Since instantaneous CNTR value is often needed to be read while the CNTR continues to count, the OTR serves as a
convenient dump site for instantaneous CNTR data which can then be read without interfering with the counting process.
PLS: Power loss indicator latch; set upon power up
U/D: Count direction indicator: 0: count down, 1: count up
S: Sign bit. 1: negative, 2: positive
A “CLR STR” command to IR resets all status bits except CEN
and U/D. In quadrature mode, if the quadrature clocks have
been halted, the status bits CY, BW and CMP are not affected
by a “CLR STR” command under the following conditions:
CY: If CNTR = FFFFFFFF with status bit U/D = 1
BW: If CNTR = 0 with status bit U/D = 0
CMP: If CNTR = DTR
In non-quadrature mode the same rules apply if input A is held at
logic low.
