5.2.6.2.5 SYNC_DELAY
E981.07
The SYNC_DELAY command is used to control the time delay between two consecutive rising edges of the four
SYNC pulses. If the eight SD bits are interpreted as an unsigned integer number, then the delay between two
consecutive SYNC pulses tSYNC_DEL can be calculated as
tSYNC_DEL = 0.5*SD µs
The default value is SD=8 (decimal), corresponding to tSYNC_DEL = 4 µs.
The response indicates the current SD value. The command is latched until a subsequent SPI update or reset
happens.

5.2.6.2.6 GRANT_TESTMODE
The GRANT_TESTMODE command must not be used except for ELMOS production test. To enter the device's
test modes two conditions have to be satisfied:
• the TEST pin has to be pulled high.
• the GRANT_TESTMODE request has to be the next SPI frame that is issued.
Within test mode, the device provides extended functionality which is used for production test purposes.
