70 SPI-4 Packet received P_CLK pulse separate
Indicates that the SPI-4 state machine after
the Receive input FIFO has received an
SPI-4 packet.
71 reserved
72 Data CFrame transmitted P_CLK level separate
Indicates that the transmit buffer state
machine is writing a CSIX Data CFRAME
into the transmit FIFO; One P_CLK cycle
indicates a 32-bit write into the transmit
FIFO.
73 Control CFrame transmitted P_CLK level separate
Indicates the transmit buffer state machine
is writing a CSIX Control CFRAME into the
transmit FIFO; One P_CLK cycle indicates a
32-bit write into the transmit FIFO.
74 SPI-4 CFrame transmitted P_CLK level separate
Indicates the transmit buffer state machine
is writing an SPI-4 Packet into the transmit
FIFO; One P_CLK cycle indicates a 32-bit
write into the transmit FIFO.
