TSIGRSYN: TSI Gap Resync Mode (For detailed information, see
ATSIGAP/BTSIGAP register description)
0: OFF
1: PLL reset after TSI Gap
MANCPAJ: Manchester code phase readjustment
0: disabled - Manchester code polarity is defined by the TSI pattern. Use as
default, if TSI 8bit GAP Mode is not used
1: enabled - the code phase readjustment will be done with each “1001” or
“0110” Manchester data change. Use for TSI 8bit GAP Mode
TSIGAP: TSI Gap (T/2 bit resolution)
1Fh: 15 1/2 bit gap
00h: 0 bit gap
TSIGAP is used to lock the PLL after TSI A is found, if the TSI detection
mode 10b is selected.
GAPVAL: TSI Gap (T/16 bit resolution)
111b: 7/16 bit gap
000b: 0 bit gap
GAPVAL is used to correct the DCO phase after TSIGAP time, if the
TSIMODE.TSIGRSYN is disabled
