Byte address
Half resolution image extraction
This is a modification of the previous reception modes, being applicable to monochrome,
RGB or Y extraction modes.
This mode is used to only store a half resolution image. It is selected through OELS and
LSM control bits.
24.4 DCMI interrupts
Five interrupts are generated. All interrupts are maskable by software. The global interrupt
(DCMI_IT) is the OR of all the individual interrupts. The table below gives the list of all
interrupts.
