ISOC
Input
H2 This input is only active in SCI-PHY/Utopia bus
slave or bus master modes (SCIANY = 1,
ANYPHY= 0).
The Input Start of Cell (ISOC) marks the start of the
cell on the IDAT[15:0] bus. When ISOC is high, the
first word of the cell structure is present on the
IDAT[15:0] stream. It is not necessary for ISOC to
be asserted for each cell, unless inband addressing
is being used. An interrupt may be generated if
ISOC is high during any word other than the first
word of the cell structure.
ISOC is sampled on the rising edge of IFCLK. If
IMASTER is high, ISOC is considered valid only
when the IENB signal was low in the previous cycle.
If IMASTER is low, ISOC is considered valid
coincident with IENB assertion.
ISX
Input
H4 The Transmit Start Of Cell (ISX) indication signal is
only active in Any-PHY bus slave mode (when
IANYPHY=1 and IMASTER=0). ISX marks the start
of cell on the IDAT[15:0] data bus. When ISX is
high, the first word of the cell structure is present on
the IDAT[15:0] stream. ISX must be asserted for
each cell. An interrupt may be generated if ISX is
high during any word other than the expected first
word of the cell structure.
This input is only active if the SCIANY input is a
logic high.
