All Rights Reserved + +\ Register access + +\ The chips that support 32-bit descriptor addresses usually +\ have two modes for accessing the control registers. In the +\ "normal" word I/O mode, the registers are accessed with 16-bit +\ bus cycles and appear at adjacent 16-bit locations (0x10, 0x12, ...) +\ In double-word I/O mode, they are accessed with 32-bit bus +\ cycles and appear at adjacent 32-bit locations (0x10, 0x14, ...) +\ In either case, they contain only 16 bits of useful data, so +\ there is no real advantage to using 32-bit accesses. +\ The chip determines the mode from the first access cycle, and +\ "locks" into that mode. The only way to change the mode thereafter +\ is to issue a hardware reset to it; a software reset won't do it. +\ We use 16-bit mode as the default, for the benefit of client programs +\ that use older driver code. + +[ifdef] 32-bit-cycles +: >reg ( offset -- adr ) la swap la+ h# 10 + ; +: reg@ ( offset -- data ) >reg rl@ ; +: reg!

Unlike the register access, there +\ is a compelling reason to use the 32-bit data structures, for +\ they contain 32-bit DMA pointers. The 16-bit data structures +\ use 24-bit DMA pointers, thus restricting DMA to the lower 16 MBytes. + +\ Message descriptor access + +struct ( message-descriptor ) +4 field >addr +2 field >bytecnt +1 field >reserved1 +1 field >laflags +0 field >tmd2 +2 field >mcnt +0 field >xerrors +1 field >rpc +1 field >rcc +4 field >reserved2 +( total-length ) constant /md + +/md value /rmd +/md value /tmd + +\ Little-endian reads and writes +: lew@ ( addr -- w ) dup c@ swap 1+ c@ bwjoin ; +: lew!
