Description
Transmitter interrupt condition
The interrupt enable bits are used to enable an
interrupt when the respective status bit is set in Serial
Channel Status A.
Table 87, “Transmitter interrupt enable bits,” on
page 228, lists individual bit numbers and
descriptions.
Enable transmit DMA requests
Enables the transmitter to interact with a DMA
channel. When configured to operate in DMA mode,
the DMA controller loads the transmit data FIFO from
memory.
Clear this bit to pause the transmitter.
