INSTRUCTION NAME: DT (dead time)
DESCRIPTION : This instruction delays the SVA output for a length of time specified by the value in
operand 1. Operand 2 contains a reset value that sets the SVA output and register stacks equal to
the SVA input. The SVA input is sampled with the period equal to 1/16 of the dead time. The SVA
output is the linear time interpolation between the current SVA output and the next output value in
the register stack. The register stack can hold up to 16 values. The SVD input remains unchanged.

OPERAND DESCRIPTIONS:
Dead time - A tuning parameter that specifies the time in minutes for the SVA input to progress
through the register stack and become the SVA output. Dead time values are: 0, or 0.0644 to
2109.85 minutes for the 4 hertz version controller; 0, or 0.0258 to 843.94 minutes for the 10 hertz
version controller; and 0, or 0.0129 to 421.97 minutes for the 20 hertz version controller.
Reset - The name of the general register or discrete loadable function that contains the reset value
(1 or 0).
Comment - A comment up to 255 characters long.
