9. RES0 to RES7: Reset Registers
These 8-byte reset registers are valid only in the ISA bus mode. Writing to these registers (any data can be
written to any of RES0 to RES7) allows initialization of the buffer manager, data link controller, Manchester
encoder/decoder, and 10BASE-T transceiver. This writing also allows the internal registers to be initialized by
a reset, but prohibits initialization of BMPR18 and BMPR19.
