12.3.1 ECP Register and Bit Map
The next two tables list the registers used in the ECP mode and provide a bit map of the parallel port
and ECP registers.
Note: The base addresses are specified by CR60 and 61, which are determined by the configuration register or the hardware
Notes:
1. These registers are available in all modes.
2. All FIFOs use one common 16-byte FIFO.
Each register (or pair of registers, in some cases) is discussed below.
