Motorola SE4750 - RD_SENSOR 0 X51; RESET 0 X57; TIME_TO_LOW_POWER 0 X75; WR_SCRIPT 0 X76

5 - 8 SE4750 Integration Guide
RD_SENSOR 0x51
Reads Aptina AR0134 sensor registers. Refer to the AR0134 specification from Aptina for register descriptions.
RESET 0x57
Returns the SE4750 to a default state.
TIME_TO_LOW_POWER 0x75
Sets the length of time the SE4750 must be idle before it enters low power mode. This only applies if
AUTO_POWER_REDUCTION is enabled.
WR_SCRIPT 0x76
Programs more than one SE4750 command into a script, which can be executed using a single command
(EXECUTE_SCRIPT). Use this method whenever possible to increase performance and timing synchronization.
There are ten scripts (Script-0 through Script-9) and a total of 150 bytes for all scripts. Exceeding these limits
results in a NAK status code. The general format for this command is:
<0x76><Script#><Len> [ <C
1
Len><C
1
Op><C

Data> ] [ <C
2
Len><C

[<C

Example
To program script 2 with AIM_ON, ILLUM_ON, and ACQUISITION_ON, format the WR_SCRIPT command as
follows:
<0x76><0x02><0x09> [ <0x02><0x55><0x01> ] [ <0x02><0x59><0x01> ] [ <0x02><0x58><0x01> ] <0x70>
WR_SENSOR 0x50
Writes directly to the Aptina AR0134 sensor registers. Refer to the AR0134 specification from Aptina for register
descriptions.
NOTE Brackets ( [ ] ) appear in this example for clarity only, and are not part of the commands.
CAUTION The SE4750 controls many sensor registers. Using this command to write sensor registers may
conflict with SE4750 requirements, causing unpredictable behavior.
