TX Port Pass
Indicates valid data is available on at least one
port, or on all ports if configured for all port
status via the CSI_PASS_MODE bit in the
CSI_CTL2 register. The function differs based
on mode of operation.
In asynchronous operation, the
TX_PORT_PASS indicates the CSI port is
actively delivering valid video data. The status
is cleared based on detection of an error
condition that interrupts transmission.
During Synchronized forwarding, the
TX_PORT_PASS indicates valid data is
available for delivery on the CSI TX output.
Data may not be delivered if ports are not
synchronized. The TX_PORT_SYNC status is
a better indicator that valid data is being
delivered to the CSI transmit port.
Reserved
RX Port Interrupt Enable
Enable interrupt based on receiver port
interrupt for the RX Ports being forwarded to
the CSI Transmit Port.
CSI Sync Error interrupt Enable
Enable interrupt on CSI Synchronization
enable.
CSI Synchronized interrupt Enable
Enable interrupts on CSI Transmit Port
assertion of CSI Synchronized Status.
CSI RX Pass Error interrupt Enable
Enable interrupt on CSI Pass Error
CSI Pass interrupt Enable
Enable interrupt on CSI Transmit Port
assertion of CSI Pass.
Reserved
RX Port Interrupt
A Receiver port interrupt has been generated
for one of the RX Ports being forwarded to the
CSI Transmit Port. A read of the associated
port receive status registers will clear this
interrupt. See the PORT_ISR_HI and
PORT_ISR_LO registers for details.
CSI Sync Error interrupt
A synchronization error has been detected for
multiple video stream inputs to the CSI
Transmitter.
CSI Synchronized interrupt
CSI Transmit Port assertion of CSI
Synchronized Status. Current status for CSI
Sync can be read from the TX_PORT_SYNC
flag in the CSI_STS register.
CSI RX Pass Error interrupt
A deassertion of CSI Pass has been detected
on one of the RX Ports being forwarded to the
CSI Transmit Port
CSI Pass interrupt
CSI Transmit Port assertion of CSI Pass
detected. Current status for the CSI Pass
indication can be read from the
TX_PORT_PASS flag in the CSI_STS register
