Manufacturer:MOT Description:Transmit Ready A-B (active low) - This function is associ- ated with 44 pin PLCC and 48 pin TQFP packages only. These outputs provide the TX FIFO/THR status for indi- vidual transmit channels (A-B). TXRDY is primarily in- tended for monitoring DMA mode 1 transfers for the trans- mit data FIFO’s. An individual channel’s -TXRDY A-B buffer ready status is indicated by logic 0, i.e., at least one location is empty and available in the FIFO or THR. This pin goes to a logic 1 when there are no more empty locations in the FIFO or THR. This signal can also be used for single mode transfers (DMA mode 0). |
