BMA456 nothing happened with ASIC

Hello support,

I am trying to make a BMA456 work at minimum through SPI bus. I send this list of command :

write 0xb6 in 0x7e
wait 500 ms

write 0x04 in 0x7d -> value check in the register OK

read 0x00 => return 0x16

write 0x00 in 0x41 => value check in the register OK

write 0x17 in 0x40 => value check in the register OK

I consult regularely :

register status 0x03 => always 0

register internal status 0x2a => always 0

What I missed in the configuration boar basic utilisation ? What I can check more ?

Thanks in advance

Mickael
