0 = At least one byte of data contains in the FIFO.
1 = FIFO is empty.
ECR Bit-1:
This read-only bit returns FIFO full status (FIFO-F)
and is forced low unless PPF, ECP, or TST mode is
selected.
0 = At least one empty location is available in the
FIFO.
1 = FIFO is full.
ECR Bit-2:
When low, this bit (ServiceIntr) enables a pulsed
interrupt and enables DMA requests (if bit-3 is set). If
the enabled interrupt occurs, this bit is automatically
returned to a high. The interrupt conditions are:
ECR Bit-3 = DMA
DCR Bit-5 = DIRection

8 empty bytes in the FIFO.
8 filled bytes in the FIFO.
DMA Terminal Count (TC).
ECR BIT-3:
This bit disables DMA when set low. When set high,
a low on ServiceIntr will enable DMA requests.
0 = DMA disabled, DRQx pin is three-stated.
1 = DMA enabled
ECR Bit-4:
When low, this bit (-ErrIntrEn) enables a pulsed inter-
rupt if -ERROR (-Fault) is low. The interrupt is only
enabled in ECP mode.
ECR Bit 5-7:
This field can be set to any value if the current value
is 000 or 001. If the current value is not 000 or 001,
then the field can only be written to 000 or 001. The
modes are defined as:
Cnfg-B Bit 0-2:
With bit 2 forced low, select an 8-bit DMA channel per
the following table:
-IOW

Cnfg-B Bit-7:
Indicates RLE compression is not supported.
EXTENDED CONTROL REGISTER ( ECR )
The Extended Control Register has a system RESET
state of 10010101. The significance of the bits is
defined by the ECP specification as:
ECR Bit-0:
This read-only bit returns FIFO empty status (FIFO-E)
and is forced high unless PPF, ECP, or TST mode is
selected.
