DELIC Strap Option Configuration
The DELIC “
Strap Status Register (CSTRAP)
” is described in the DELIC-LC PEB
20570/DELIC-PB PEB 20571 Data Sheet, independent of the version (2.1 .. 3.1). The
register description (see updated register
CSTRAP
) of the Data Sheet is misleading
concerning bit 0 and 1. They are
not
configured by strap option. For a stable DCXO
synchronization it is recommended to proceed as follows:
1. After Boot read register CSTRAP to detect the value
2. Set only bit CSTRAP:
DCXO
to ’
0
’ and set the others as detected before
