cnfg_ref_selection_priority_8
This 4-bit value represents the relative priority of
input I8. The smaller the number, the higher the
priority; zero disables the input.
*When Bit 4 (T4_T0_select) of Reg. 4B
(cnfg_registers_source_select) = 0 the priority for
the T0 path is configured.
When this Bit 4 = 1 the priority for the T4 path is
configured.
cnfg_ref_selection_priority_7
This 4-bit value represents the relative priority of
input I7. The smaller the number, the higher the
priority; zero disables the input.
*When Bit 4 (T4_T0_select) of Reg. 4B
(cnfg_registers_source_select) = 0 the priority for
the T0 path is configured.
When this Bit 4 = 1 the priority for the T4 path is
configured.
0000
Input I8 unavailable for automatic selection.
0001-1111 Input I8 priority value.
0000
Input I7 unavailable for automatic selection.
0001-1111 Input I7 priority value.
