7000_4C00h [22:20] TSADC input sequence control.
When bit [2] is 0, the TSADC input is
entirely determined by the settings
of ts_muxctrl1 and ts_muxctrl2.
When bit [2] is 1, MUX2 auto-
sequences its input using the
pattern in the table below. If the
sequence includes MUX2 input 7
(MUX1), the source in this time slot
is determined by the setting of
ts_muxctrl1.
0 to 3: Defined by ts_muxctrl1,2
4: Auto-sequence: 1, 2, 1, 3, 1, 2, 1, 4
5: Auto-sequence: 1, 5, 1, 3, 1, 7, 1, 4
6: Auto-sequence: 1, 5, 2, 3, 1, 7, 2, 4
7: Auto-sequence: 1, 5, 2, 3, 1, 7, 6, 4
