Stream Monitor configuration. This register is used to configure the CSIRX Monitors: Programmable Frame monitor to trigger an event if a truncated frame is detected, Programmable Timer to trigger an event based on a clock cycle counter after a frame start or frame end, Programmable line/byte counters to trigger an event at a specific byte in a line. This register is used to enable/disable CSIRX programmable interrupt, select the virtual channel for each programmable IT and select the point which will trigger the event. This register should not be modified while the data path is enabled, nor should any of settings be changed when the respective monitor/counter/timer is enabled. In these cases, the behaviour is unpredictable. Hard reset value is 0x00000000, all interrupt generators disabled on Virtual Channel 0.

uint16_t CSIRX_StreamMonitorCtrl::frameLength |
Indicates the frame length in lines to detect truncated frames. This value must not change while monitor is enabled, i.e. it must only be changed when the FrameMonEn bit is low. 0x0000 means truncated frame detection feature disabled
uint8_t CSIRX_StreamMonitorCtrl::frameMonEn |
Enables monitor. This bit must only be set high after the FrameMonVc and FrameLength have been set.
uint8_t CSIRX_StreamMonitorCtrl::frameMonVc |
Indicates virtual channel for monitor. This value must not change while monitor is enabled, i.e. it must only be changed when the FrameMonEn bit is low.
uint8_t CSIRX_StreamMonitorCtrl::timerEof |
Select the starting point of the timer: 0x0: Start of Frame event on selected virtual channel 0x1: End of Frame event on selected virtual channel. This value must not change while timerEn is enabled
uint8_t CSIRX_StreamMonitorCtrl::timerEn |
Enables timer based interrupt. This bit must only be set high after the timerEof and timerVc have been set.
uint8_t CSIRX_StreamMonitorCtrl::timerVc |
Indicates which VC should be used to generate timer based interrupt. This value must not change while timerEn is enabled.
uint8_t CSIRX_StreamMonitorCtrl::lbEn |
Enables line/byte counter. This bit must only be set high after the LbVc, LineCount and ByteCount have been set.
uint8_t CSIRX_StreamMonitorCtrl::lbVc |
Indicates which VC should be used to generate line/byte counter interrupt. This value must not change while lbEn is enabled
