10.3. I2C register description
Address Register name
Configuration
0x00 ACQ_TX_CONF_I2C
Ref. Description
Table 6 Acquisition and transmission configuration
0x01 BW_VIDEO_CONF_IC2
Use this register to overwrite the values set by the corresponding configuration
pins (see Table 2 or Table 3). Make sure RD_CONF_CTRL is set to 1. In this case
ACQ_TX_CONF_I2C is copied to ACQ_TX_CONF_EFF at the rising edge of
Read Pulse.
Table 7 Bandwidth control of the video amplifier
Use this register address to overwrite the values set by the corresponding configu-
ration pins (see Table 2 or Table 3). Make sure RD_CONF_CTRL is set to 1. In
this case BW_VIDEO_CONF_IC2 is copied to BW_VIDEO_CONF_EFF at the ris-
ing edge of Read Pulse.
0x02 MISC_CONF
Table 8 Miscellaneous configuration
0x03 ACQ_TX_CONF_EFF
Table 6 Acquisition and transmission configuration (effective register)
The values for this register are read in from the configuration pins as long as
RD_CONF_CTRL is set to 0
Do not write to this register through I2C, use ACQ_TX_CONF_I2C instead.
0x04 BW_VIDEO_CONF_EFF
Table 7 Bandwidth control of the video amplifier (effective register)
The values for this register are read in from the configuration pins as long as
RD_CONF_CTRL is set to 0
Do not write to this register through I2C, use BW_VIDEO_CONF_IC2 instead.
