Disables the interrupt generated on the asserting edge of nFault.
Enables an interrupt pulse on the high to low edge of nFault. Note that an interrupt will be
generated if nFault is asserted (interrupting) and this bit is written from a 1 to a 0. This prevents
interrupts from being lost in the time between the read of the ecr and the write of the ecr.
Enables DMA (DMA starts when serviceIntr is 0).
Disables DMA unconditionally.
Disables DMA and all of the service interrupts.
Enables one of the following 3 cases of interrupts. Once one of the 3 service interrupts has
occurred serviceIntr bit shall be set to a 1 by hardware. It must be reset to 0 to re-enable the
interrupts. Writing this bit to a 1 will not cause an interrupt.
During DMA (this bit is set to a 1 when terminal count is reached).
This bit shall be set to 1 whenever there are writeIntrThreshold or more bytes free in the FIFO.
This bit shall be set to 1 whenever there are readIntrThreshold or more valid bytes to be read from
The FIFO cannot accept another byte or the FIFO is completely full.
The FIFO has at least 1 free byte.
The FIFO is completely empty.
The FIFO contains at least 1 byte of data.
