Description

4000-4049

integer

(16 bits)

Value placed in a 16-bit register.

7000-7019

float (32 bits)

Value placed in two successive 16-bit

registers. Registers include the same

data as 32-bit register from the area 7500.

Registers are only for readout.

7200-7327

float (32 bits)

Value placed in two successive 16-bit

registers. Registers include the same

data as 32-bit register from the area 7600.

Registers can be read out and written.

float (32 bits) Value placed in a 32-bit register. Registers

are only for readout.

7600-7663

float (32 bits)

Value placed in a 32-bit register. Registers
can be read out and written.
