during power-up, the Serial interface will first act as a master device, trying to read from an external

EEPROM (24C02/04/08/16). The first word read will indicate the number of bytes to transfer from the

external EEPROM. After transferring these bytes, or failing to access an external device, the

ICM-532B will behave like a slave device. The external EEPROM is addressed at address 0x50, and

must be 3.3v compatible.

PART_CONTROL

Processing control

[0] 0: normal mode

[1] Slope adjustment enable

[2] Exposure time control, writing a 1 will activate

the new value set in AD_EXPOSE_TIME, when

read back from it, 0 means the exposure time

change is finished, 1 means the exposure time

change is still in progress.

[6:3] Reserved

[7] Latent change, writing a 1 means the changed

latent registers now starts taking effect, when the

entire operation is done, the read back value of this

bit will change from 1 to 0.

Timing control

[0] Column count enable, set to 0 when filling wave

table, set to 1 when normal operation

[3] Auto dark correction enable

[4] Timing select, 0: wave table timing, 1: default

timing

[8] IRST select, 0: from wave table, 1: from

IRST_NUMBER register

[11] Dead column removal mode, 0: color, 1:

black-and-white

[12] Out-of-array exposure pointer control, 0: point

to row 295, 1: point to row 298 (a non-existent row)

[13] Column stop, 0: sensor column counter stop at

361 when exceeding real array, 1: sensor column

counter keeps counting
