Can trn_tsrc_rdy_n be asserted all the time? When should trn_tsrc_rdy_n be asserted?
The user application input trn_tsrc_rdy_n should not be asserted low all the time. It should only be asserted when the user application is involved in a data transfer. It should be asserted at the same time as trn_tsof_n and deasserted with trn_teof_n. It is permissible to insert wait states between the assertions of trn_sof_n and trn_teof_n by deasserting trn_tsrc_rdy_n.
