Bit Value Value Description
3rd highest priority validated source
Reports the input channel number of the 3rd highest
priority validated source.
When Bit 4 (T4_T0_select) of Reg. 4B
(cnfg_registers_source_select) = 0 the 3rd highest
priority validated source for the T0 path is reported.
When this Bit 4 = 1 the value will always be zero as
the T4 path does not maintain the 3rd highest
priority validated source.

highest priority validated source.
When Bit 4 (T4_T0_select) of Reg. 4B
(cnfg_registers_source_select) = 0 the 2nd highest
priority validated source for the T0 path is reported.
When this Bit 4 = 1 the 2nd highest priority validated
source for the T4 path is reported.
