4.4 Channel Interrupt Processing Flow
Figure 4-5 illustrates the ow of a channel interrupt. Note that this does not describe the
processing of the global interrupts GUN and GOV.
14
TXB
Tx buffer
0 = No TXB event has occurred.
1 = A buffer has been completely transmitted. This bit is set (and an interrupt request is
generated) as soon as the programmed number of PAD characters (or the closing ag, for
PAD = 0) is written to the SCC’s transmit FIFO. The number of PAD characters determines
the timing of the TXB interrupt in relation to the closing ag sent out at TXD. See
Chapter 5, “Buffer Descriptors,” for an explanation of PAD characters and their use.
15
RXB
Rx buffer
0 = No RXB event has occurred.
1 = A buffer has been received on this channel.
