CXD2409R
Serial input (IRENB = low, PS = low)
By inputting 8-bit data to the ED2 pin (Pin 23), the electronic shutter speed can be controlled.
Serial input data format
SPDNV/ED2
D7 D6 D5 D4 D3 D2 D1 D0
IRIN/ED1
SPUPV/ED0
The ED2 (Pin 23) data is latched in the register at the ED1 (Pin 20) rise, and retrieved internally at the ED0
(Pin 24) rise.
