The bit definitions are as follows:
Bit 7: This bit is read-only. It is logical 0 during a read, which means that this chip does not support
hardware RLE compression.
Bit 6: Returns the value on the ISA IRQ line to determine possible conflicts.
Bit 5-3: Reflects the IRQ resource assigned for ECP port.
Bit 2-0: These five bits are logical 1 during a read and can be written.
10.3.10 ECR (Extended Control Register) Mode = all
This register controls the extended ECP parallel port functions. The bit definitions are follows:
