- Set the appropriate
c0_ctrl_tx_soft_flush
throughc3_ctrl_tx_soft_flush
fields of the corresponding C0_CTL_TX_MAIN_REG through C3_CTL_TX_MAIN_REG registers to 1 for the selected port. This step is required to flush any context remaining in the memories from previous operations. It is important that no traffic is present on the selected port. - Clear the
cavp_tx_enc_req_en

c0_ctrl_tx_soft_flush
throughc3_ctrl_tx_soft_flush
fields of the corresponding C0_CTL_TX_MAIN_REG through C3_CTL_TX_MAIN_REG registers to 0 for the selected port. - From this point, functional operation can resume including re-configuration of the HSC Subsystem to a new mode, or a new port can be selected for CAVP.
