SPI-3 Input Data Word Modulo: These 2 inputs
indicate the number of valid data bytes in ISPID(31-
0). The ISPIMOD bus should always be all zero,
except during the last double-word transfer of a
frame on ISPID(31-0).
00 - ISPID(31-0) Valid
01 - ISPID(31-8) Valid
10 - ISPID(31-16) Valid
11 - ISPID(31-24) Valid
SPI-3 Input Start of Frame: This active high input is
used to delineate the frame boundaries on the
ISPID(31-0) bus. When ISPISOP is high, the start of
the frame is present on ISPID(31-0).
SPI-3 Input End of Frame: This input signal is used
to delineate the frame boundaries on the ISPID(31-
0) bus. When high, the end of the frame is present
on ISPID(31-0).
SPI-3 Input Error Indicator: This active high input
signal is used to indicate that the current frame
should be discarded.
SPI-3 Input PHY Mode Transmit Start of Transfer:
This active high input signal indicates when the in-
bound port address is present on ISPID(31-0).
SPI-3 Input PHY Mode Transmit Write Enable:
This active low input signal is used to control the flow
of data to the transmit FIFOs.
SPI-3 Input PHY Mode Transmit Address: 8-bit
bus containing the PHY address. ISPITADR7 is
MSB.
SPI-3 Input PHY Mode Selected Transmit Packet
Available: Active high output used to indicate that
space is available in the Egress FIFO specified on
the inbound address on ISPID(31-0). This signal is
used only for byte level flow control.
SPI-3 Input PHY Mode Polled Transmit Packet
Available: Active high output used to indicate that
space is available in the polled Egress FIFO. This
signal is used only for packet level flow control.
