Bit #:
Binary:
Hex ($):
Bits [31 – 16]
specify the command code. This field is protocol specific.
Bits [15 – 14]
specify the parity. This field is protocol specific.
Bit 13
specifies the trigger mode.
Bit 12
is the trigger enable toggle.
Bit 11
specifies the conversion type. This field is protocol specific.
Bit 10
is the data ready bit, read only.
Bits [9 – 6]
specify the encoder status field. This field is protocol specific.
Bits [5 – 0]
specify the serial encoder bit length (single-turn + multi-turn).
Following, are examples for setting up the control and command words for each of the supported protocols.
Also, the resulting data registers and their format.
