the timing for a period of H output of preamble B synchronization signal PB and bit 0 data output (c0 Lch, c0 Rch) of
channel status is shown on the following figure.
Possible to output channel status data from EMPHA/UO/CO by switching PBSEL1 that performs the setting of
Polarity of RLRCK is uncertain because channel status data loads data and outputs them on each sub-flame. However,
Possible to output preambles B synchronization signal that is block synchronization of channel status from
by switching the content of
For the period that bit 0 data of the channel status is output, PB signal outputs H. For the otherwise period, it outputs L.
Regarding PBSEL [1:0], possible to output preamble B synchronization signal with DIT function. However,
impossible to set output preamble B with DIR function and DIT function from PB at once because they share the
terminal.
In case of setting preamble B synchronization signal output with DIR function, the channel status data is output from
EMPHA/UO/CO pin, and the setting of UOSEL is invalid.
