CMOS Sensor Interface
The CMOS Sensor Interface (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.
4.14.1
Gated Clock Mode
Figure 63 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 64 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 35.

1 All the timings for the SSI 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.
2 There are 2 set of I/O signals for the SSI module. They are from Port C primary function (pad 257 to pad 261) and Port B
alternate function (pad 283 to pad 288). When SSI signals are configured as outputs, they can be viewed both at Port C primary
function and Port B alternate function. 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 are selected from Port C primary function.
