+
+\ 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! ( data offset -- ) >reg rl! ;

+
+
+\ In addition to the 16/32-bit register access, some AMD Ethernet
+\ chips allow you to choose 16-bit and 32-bit versions of the
+\ descriptor data structures. 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.

+\ 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.

+\ In addition to the 16/32-bit register access, some AMD Ethernet
+\ chips allow you to choose 16-bit and 32-bit versions of the
+\ descriptor data structures. 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.
