CXD2452R
Detailed Description of Each Data
D00 to D07 CHIP
The serial interface data is loaded to the CXD2452R when D00 and D07 are 1. However, this assumes that
either the EBCKSM pin is low and D64 to D71 CHKSUM is satisfied or the EBCKSM pin is high.
D08 to D15 CTGRY
Of the data provided to the CXD2452R by the serial interface, the CXD2452R loads D16 and subsequent data
to the control register side when D08 is 0, and to the adjustment register side when D08 is 1. However, this
assumes that the CXD2452R is selected by CHIP and that either the EBCKSM pin is low and D64 to D71
CHKSUM is satisfied or the EBCKSM pin is high.

D16 to D35 Electronic shutter mode
The CXD2452R's electronic shutter mode can be switched as follows by SMD D16 to D17 . Handling of the
data from D18 to D35 differs according to the mode, and is explained in detail below.

[XSUB stopped mode]
During this mode, the data from D18 to D35 is invalid. The shutter speed is 1/60s during monitoring drive
mode, and 1/30s during recording drive mode.
Shut.HD is expressed as 1C3h .
Note that when SEN is shared with other ICs and indentification is performed using CHIP-ID, the CXD2452R
data must be positioned immeditately before the load timing, that is to say at the very end.
Note that the CXD2452R cannot apply both categories simultaneously during the same vertical interval. Also,
care should be taken as the data is overwritten even if the same category is applied.
