Type
SPI-3 Output Bus Parity: This output signal indicates
the parity calculated over OSPID(31-0) bus.
SPI-3 Output Data Word Modulo: These 2 inputs
indicate the number of valid data bytes in OSPID(31-0).
The OSPIMOD bus should always be all zero, except
during the last double-word transfer of a frame on
OSPID(31-0).
00 - OSPID(31-0) Valid
01 - OSPID(31-8) Valid
10 - OSPID(31-16) Valid
11 - OSPID(31-24) Valid
SPI-3 Output Start of Frame: This active high input is
used to delineate the frame boundaries on the
OSPID(31-0) bus. When OSPISOP is high, the start of
the frame is present on OSPID(31-0).
SPI-3 Output End of Frame: This output signal is used
to delineate the frame boundaries on the OSPID(31-0)
bus. When OSPIEOP is high, the end of the frame is
present on OSPID(31-0).
SPI-3 Output Error Indicator: This active high output
signal is used to indicate that the current frame is
aborted and should be discarded.
SPI-3 Output PHY Mode Receive Start of Transfer:
This active high output signal indicates when the in-
bound port address is present on OSPID(31-0).
SPI-3 Output PHY Mode Receive Read Enable: This
active low input signal is used to control the flow of data
from the Ingress FIFOs.
SPI-3 Output PHY Mode Receive Data Valid: Active
high output signal that validates the OSPID(31-0),
OSPIPRTY, OSPIMOD(1:0), OSPISOP, OSPIEOP, and
OSPIERR signals. OSPIRVAL will transition low when
the receive FIFO is empty or at the end of a frame.
SPI-3 Output Link Mode Transmit Write Enable:
Active low write enable signal.
SPI-3 Output Link Mode Transmit Address: Address
in Link mode for addressing Multiple PHY devices.
OSPITADR7 is MSB.
