L9679BB

Deployment

Diagnostic

The high side driver diagnostic, described in section on page

167, doesn’t work. As a consequence, the ILIM_HS_FET parameter

is not tested in production.

L9679BB

Safing

engine

The safing records associated with CS_RS validate and process

data with matching request/response masks even if these are not

coming from CS_RS frames but from frames sniffed on

SAF_CSx.

This may lead to issues when expansion chip is used and

CS_RS frames sent on expansion are sniffed by SAF_CSx at

SBC side; the SBC fails to check its own CS_RS and therefore

all RSUs safing records CC with matching request/response

masks of expansion RSUs safing records will be updated upon

the processing of the expansion RSU SPI data.

Workaround: use two different values for WID SPI bit when

addressing CS_RS at SBC (ie WID=1) and expansion (WID=0)

side.
