transmit mode the two interrupt signals are IRQ0 and IRQ1. IRQ1 is mapped to IRQCFG0D_FIFOFULL[2] signal
indicating that the transmission FIFO is full when IRQCFG0D_TX_IRQ1[3] is set to 0, or to IRQCFG0E_TX_
STOP[5] when IRQCFG0D_ TX_IRQ1[3] is set to 1. IRQ0 is mapped to the IRQCFG0D_nFIFOEMPY[1] signal.
This signal indicates the transmitter FIFO is empty and must be refilled with data to continue transmission.
3.7 IRQ0 and IRQ1 Mapping
Two TRC105 outputs are dedicated to host microcontroller interrupts or signaling. The interrupts are IRQ0 and
IRQ1 and each have selectable sources. Tables 10, 11, 12 and 13 below summarize the interrupt mapping op-
tions. These interrupts are especially useful in Continuous or Buffered data mode operation.
Tables 12 and 13 describe the interrupts available in transmit mode:
