Bit 4: Read/Write (Valid only in ECP Mode)
1
Disables the interrupt generated on the asserting edge of nFault.
0
Enables an interrupt pulse on the high to low edge of nFault. If nFault is asserted
(interrupt) an interrupt will be generated and this bit is written from a 1 to 0.
Bit 3: Read/Write
1
0
Enables DMA.
Disables DMA unconditionally.
Bit 2: Read/Write
1
0
Disables DMA and all of the service interrupts.
Enables one of the following cases of interrupts. When one of the service interrupts
has occurred, the serviceIntr bit is set to a 1 by hardware. This bit must be reset to 0
to re-enable the interrupts. Writing a 1 to this bit will not cause an interrupt.
(a) dmaEn = 1: During DMA this bit is set to a 1 when terminal count is reached.
(b) dmaEn = 0 direction = 0: This bit is set to 1 whenever there are writeIntr Threshold
or more bytes free in the FIFO.
(c) dmaEn = 0 direction = 1: This bit is set to 1 whenever there are readIntr Threshold
or more valid bytes to be read from the FIFO.
Bit 1: Read only
0
1
The FIFO has at least 1 free byte.
The FIFO cannot accept another byte or the FIFO is completely full.
Bit 0: Read only
0
1
The FIFO contains at least 1 byte of data.
The FIFO is completely empty.

Notes:
1. These registers are available in all modes.
2. All FIFOs use one common 16-byte FIFO.
