• Manufacturer: Infineon Technologies Corporation

• SACCO-B0 input clocks
• SACCO-B1 clocks
• SIDEC clocks
Semiconductor Group
– There are two SACCO-B0 clocks, HFS and HDC. Each one may be selected from
– HFS:
– HDC:
– There are two SACCO-B1 clocks, HFS and HDC. Each one may be selected from
– HFS:
– HDC:
– The SIDEC module includes four HDLC controllers. Each one receives HDC and
– The HDC clocks are driven by DCL.
Input:
Output: DCL driven by selected PDC (PDC4, PDC8). ((ELIC0:CMD1:CSS = ‘1’)
Note:
several possible sources as SACCO-B0 can be connected to the IOM signaling
mux, to the PCM signaling mux or directly to the IO when in stand-alone mode.
HFS sources:
PORT3/HFSB0 input pin, when disconnected from both PCM and IOM signaling
muxes.
FSC, when SACCO-B0 is connected to the IOM signaling mux.
PFS, when SACCO-B0 is connected to the PCM signaling mux.
HDC sources:
PDC2, PDC4, PDC8, DCL – when disconnected from both signaling muxes
(CCSEL1[5:4]). Each of these signals can be an inputs or an outputs, according to
the configuration.
PDC when SACCO-B0 is connected to the PCM signaling mux.
DCL when SACCO-B0 is connected to the IOM signaling mux.

HFS sources:

DCL when SACCO-B1 is connected to the IOM signaling mux.
HFS clocksfrom the IOM-2 interface.
DCL driven by IO ((ELIC0:CMD1:CSS = ‘1’) and (CCSEL1[2] = ‘1’))
and (CCSEL1[2] = ‘0’)) PDC4, 8 can be inputs or outputs, depends if the
DOC is master or slave.
When DCL is input or driven directly from PDC4/8, it should be used as an
input by ELIC0 and ELIC1.
