3.22.2.6 Interrupt
Note 1: Interrupts are generated not by the number of bytes stored in the FIFO buffer but by the number of bytes
written to the FIFO buffer. For example, let us assume that 32 bytes have been written into the FIFO and an
interrupt has been generated. In this case, if another byte is read and then another byte is written brinnging the
total number of bytes in the FIFO buffer to 32 bytes, a new interrupt will not be generated. This is because only
one byte has been written to the FIFO buffer. For details, see Figure 3.22.5.
Mask bits and flags corresponding to each interrupt are available. Both interrupts are
level-sensitive. Each interrupt flag is cleared by a write to the relevant register.
The CMOS image sensor can generate two types of interrupts.
• Interrupt in synchronization with external input signals (CMOSHBK or
• At the point when a specified size is written to the FIFO buffer
CMSHSY synchronization when CMSCR<CINTSEL> = 0
CMOSHBK synchronization when CMSCR<CINTSEL> = 1
