sts_priority_table
Description
3
Reports the input channel number of the 3
priority validated source.
Note...If an input is valid and it does not appear in
this field when otherwise it might, then the input
may have been disallowed in Reg. 30 and Reg. 31
(cnfg_sts_remote_sources_valid).
*When Bit 4 (T4_T0_select) of Reg. 4B
(cnfg_registers_source_select) = 0 the 3
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 3
priority validated source.
2
Reports the input channel number of the 2
highest priority validated source.
Note...If an input is valid and it does not appear in
this field when otherwise it might, then the input
may have been disallowed in Reg. 30 and Reg. 31
(cnfg_sts_remote_sources_valid).
*When Bit 4 (T4_T0_select) of Reg. 4B
(cnfg_registers_source_select) = 0 the 2
priority validated source for the T0 path is reported.
When this Bit 4 = 1 the 2
source for the T4 path is reported.
