CTR CTR

INSTRUCTION NAME: CTR (counter / ramp)

DESCRIPTION: This instruction counts the logic 0 to logic 1 transitions of the SVD input. The

SVA and SVD output values depend on the present state of the SVD input, the counter/ramp value

in operand 1, and the reset value in operand 2. Each transition of the SVD input increments an

internal counter by 1 count. If the reset value in operand 2 is 0, the SVA output is set equal to the

internal count. When the internal count equals the value in operand 1, the SVD output is 1. When

the reset value in operand 2 is 1, the SVD output and the internal count are reset to 0. Note that the

internal count can exceed the value specified in operand 1.

OPERAND DESCRIPTIONS:

Counter/ramp value - A tuning parameter that specifies the value to which the internal counter is

compared. Counter/ramp values are 0 to 2,147,480,000.

Reset - The name of the general register or discrete loadable function that contains the discrete

reset value.

Comment - A comment up to 255 characters long.
