DCMI interrupt enable register (DCMI_IER)

Address offset: 0x0C
Reset value: 0x0000 0x0000

The DCMI_IER register is used to enable interrupts. When one of the DCMI_IER bits is set,
the corresponding interrupt is enabled. This register is accessible in both read and write.
Bits 31:5 Reserved, must be kept at reset value.
Reserved
Bit 4 LINE_IE: Line interrupt enable
0: No interrupt generation when the line is received
1: An Interrupt is generated when a line has been completely received
Bit 3 VSYNC_IE: VSYNC interrupt enable
0: No interrupt generation
1: An interrupt is generated on each VSYNC transition from the inactive to the
active state
The active state of the VSYNC signal is defined by the VSPOL bit.
Bit 2 ERR_IE: Synchronization error interrupt enable
0: No interrupt generation
1: An interrupt is generated if the embedded synchronization codes are not
received in the correct order.
Note: This bit is available only in embedded synchronization mode.
Bit 1 OVR_IE: Overrun interrupt enable
0: No interrupt generation
1: An interrupt is generated if the DMA was not able to transfer the last data
before new data (32-bit) are received.
Bit 0 FRAME_IE: Capture complete interrupt enable
0: No interrupt generation
1: An interrupt is generated at the end of each received frame/crop window (in
crop mode).
