CSI Module Operation
MOTOROLA
CMOS Sensor Interface Module
31-3
31.3.1 Pin Configuration for CSI
Table 31-3 lists the pins used for the CSI module. These pins are multiplexed with other functions on the
device, and must be configured for CSI operation.
NOTE:
The user must ensure that the data direction bits in the GPIO are set to the
correct direction for proper operation. See Section 32.5.1, “Data Direction
Registers,” on page 32-9 for details.
31.4 CSI Module Operation
The following sections describe the operation of the CSI module’s data FIFO and interrupts.
31.4.1 Data FIFO Operation
The CSI module features an integrated 32
×
32-bit FIFO for the image data and a 16
×
32-bit FIFO for
statistic data. FIFO access is achieved by reading the CSI RxFIFO Register 1 and CSI Statistic FIFO
Register 1.
