4.12.10 Image Processing Unit (IPU) Module Parameters
The purpose of the IPU is to provide comprehensive support for the flow of data from an image sensor
and/or to a display device. This support covers all aspects of these activities:
• Connectivity to relevant devices—cameras, displays, graphics accelerators, and TV encoders.
• Related image processing and manipulation: sensor image signal processing, display processing,
image conversions, and other related functions.
• Synchronization and control capabilities, such as avoidance of tearing artifacts.
IC9 Bus free time between a STOP and START condition 4.7 — 1.3 — µs

1
A device must internally provide a hold time of at least 300 ns for I2Cx_SDA signal to bridge the undefined region of the falling
edge of I2Cx_SCL.
2
The maximum hold time has only to be met if the device does not stretch the LOW period (ID no IC5) of the I2Cx_SCL signal.
3
A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system, but the requirement of Set-up time (ID No IC7)
of 250 ns must be met. This automatically is the case if the device does not stretch the LOW period of the I2Cx_SCL signal.
If such a device does stretch the LOW period of the I2Cx_SCL signal, it must output the next data bit to the I2Cx_SDA line
max_rise_time (IC9) + data_setup_time (IC7) = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-bus specification)
before the I2Cx_SCL line is released.
