Reset value:
FSAD2..0
MAC
PACT
PSS
STOK
Note: This bit is only valid, if no power failure or inappropriate clocking occurred during
Semiconductor Group
the test (see ISTA:IR); this bit is set to 1 by a start selftest command or by
hardware reset.
Status Register (STAR)
Bit 7
0
FSAD2 FSAD1 FSAD0
Frame Synchronization signal Address: see CMDR.
Memory Access Active; an indirect memory access is active, if this
bit is “1”, all memory access registers must not be written until
MAC = “0”.
Procedure Active; one of the procedures started by the P (selftest,
CM reset or frame evaluation) is active.
PCM Synchronization Status
1: the PCM interface is synchronized
0: the PCM interface is not synchronized. (see note in chapter 4.5)
Selftest O.K.; after a selftest procedure this bit is set to 1, if no faults
are detected.
