IMASTER
Input
A6 The input port master select (IMASTER) pin
determines the direction of the input port cell
interface control signals.
If IMASTER is low, the input port of the S/UNI-
DUPLEX is a bus slave and complies with the SCI-
PHY/Utopia or Any-PHY transmit protocol
depending of the state of the IANYPHY input. The
IADDR[4:0], IAVALID, IENB signals are inputs. The
ICA signal is an output.
If IMASTER is high, the input port of the S/UNI-
DUPLEX is a bus master and complies with the
SCI-PHY/Utopia receive protocol (IANYPHY must
be set to low if IMASTER is high). The IADDR[4:0],
IAVALID, IENB signals are outputs. The ICA signal
is an input.
This input is only active if the SCIANY input is a
logic high.
IBUS8
IFCLK
Input
Input
C6 The input port bus width select (IBUS8) selects the
interface bus width. When IBUS8 is high, only
IDAT[7:0] are expected to present valid data and
IDAT[15:8] are ignored. When IBUS8 is low, all
IDAT[15:0] inputs are used.
This input is only active if the SCIANY input is a
logic high.
F4 The input FIFO clock (IFCLK) is used to read words
into the S/UNI-DUPLEX upstream cell buffer.
IFCLK must cycle at a 52 MHz or lower
instantaneous rate. All SCI-PHY/Any-PHY input
port timing is relative to the rising edge of IFCLK.
This input is only active if the SCIANY input is a
logic high.
