Description
When PARALLEL_ESI/ is asserted,
this signal contains bit 0 of a data
nibble for read and write operations.
When PARALLEL_ESI/ is
deasserted, this signal is the SEL_0
signal, included for compatibility with
SFF-8045.
When PARALLEL_ESI/ is asserted,
this signal contains bit 1 of a data
nibble for read and write operations.
When PARALLEL_ESI/ is
deasserted, this signal is the SEL_1
signal, included for compatibility with
SFF-8045.
When PARALLEL_ESI/ is asserted,
this signal contains bit 2 of a data
nibble for read and write operations.
When PARALLEL_ESI/ is
deasserted, this signal is the SEL_2
signal, included for compatibility with
SFF-8045.
When PARALLEL_ESI/ is asserted,
this signal contains bit 3 of a data
nibble for read and write operations.
When PARALLEL_ESI/ is
deasserted, this signal is the SEL_3
signal, included for compatibility with
SFF-8045.
