When this policy is active, it drives the *READY signal 0 for low_time cycles and then drives 1 for high_time cycles.
Note: The *READY does not drop until the specified number of cycles has occurred. The policy repeats until the channel is given a different policy.
This Figure shows that following event A, there is a delay of low_time ACLKs, then READY is asserted. After high_time cycles of ACLK, READY is deasserted and the counter restarts at A.
