Figure 10. FIFO access sequence in asynchronous mode

A3G4250D

No

WTM = ‘1’

Yes

Read FIFO SRC (2Fh)

n = FSS<4-0>

Dummy Read from ‘28h’

(increment bit =‘0’)

n--

Burst Read from ‘2Ah’ of

6 registers (Y, Z, X)

No

Yes

n=0

Example:

FSS = 1 read twice

FSS = 2 read 3 times

AM10248V1

If the above sequence is not followed, the acquisition from FIFO may lead to corrupted data.
