I want to use EPP mode of the parallel port 0;
In the document ' ET100LX_14_Parallel_Ports_010215.pdf'
find that "The read/write functionality of the EPP mode
is implemented by a configuration of the parallel port
registers . Bits 11 and 2 to 0 in register R_PAR0_CONFIG
or ... and bit 11 acts as the extended mode selector"
but in the document 'regdef.pdf' find that "R_PAR0_CONFIG
bit 11 " is defined 'reserved' ; and not define 'EPP mode'
in bit 2-0; by the way i don't find the register R_PAR0_DATA
in the document 'regdef.pdf'
Any help would be apreciated, thanks.
