Functions
RESET_RIGHT_SHIFTER
SHIFT REGISTER API

Overview

The RESET_RIGHT_SHIFTER procedure resets the right shift register a resource_domain to its default state. In order to successfully reset the shift register, the RESET_RIGHT_SHIFTER procedure call must stay asserted for at least two consecutive clock cycles. This means the RESET_RIGHT_SHIFTER procedure call will almost always appear within a state machine state in conjunction with a TRANSITION procedure call that ensures that the state_reg is held in that state for at least two clock cycles.
