Specifications
3.22 CMOS Sensor Interface
The CSI module consists of a control register to configure the interface timing, a control register for statistic data
generation, a status register, interface logic, a 32
×
32 image data receive FIFO, and a 16
×
32 statistic data FIFO.
3.22.1 Gated Clock Mode
Figure 68 shows the timing diagram when the CMOS sensor output data is configured for negative edge and the
CSI is programmed to received data on the positive edge. Figure 69 on page 89 shows the timing diagram when the
CMOS sensor output data is configured for positive edge and the CSI is programmed to received data in negative
edge. The parameters for the timing diagrams are listed in Table 42 on page 89.

1.
All the timings for both SSI modules are given for a non-inverted serial clock polarity (TSCKP/RSCKP =
0) and a non-inverted frame sync (TFSI/RFSI = 0). If the polarity of the clock and/or the frame sync have
been inverted, all the timing remains valid by inverting the clock signal STCK/SRCK and/or the frame sync
STFS/SRFS shown in the tables and in the figures.
There is one set of I/O signals for the SSI2 module. They are from Port C alternate function (PC19 –
PC24). When SSI signals are configured as outputs, they can be viewed at Port C alternate function a.
When SSI signals are configured as inputs, the SSI module selects the input based on FMCR register bits
in the Clock controller module (CRM). By default, the input is selected from Port C alternate function.
bl = bit length; wl = word length
