RX FIFO/RHR status for individual receive channels (A-B). RXRDYn is primarily intended for monitoring DMA mode l transfers for the receive data FIFOs. A logic o indicates there is a receive data to read/upload, i.e., receive ready status with one or more RX characters available in the FIFO/RHR. This pin is a logic l when the FIFO/RHR is empty or when the programmed trigger level has not been reached. This signal can also be used for single mode transfers (DMA mode 0). Transmit Ready A, B (Active-LOW). This function is associated with PLCC44 and LQFP48 packages only. These outputs provide the
