Default Value (T0)* (T4)* 0011 0010 0000 0000 Bit 7Bit 6 Bit 5Bit 4 Bit 3Bit 2 Bit 1Bit 0 cnfg_ref_selection_priority_2 cnfg_ref_selection_priority_1 Bit No. Description Bit Value Value Description [7:4] cnfg_ref_selection_priority_2 This 4-bit value represents the relative priority of input I2. 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 0001-1111 Input I2 unavailable for automatic selection. Input I2 priority value. [3:0] cnfg_ref_selection_priority_1 This 4-bit value represents the relative priority of input I1. 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 0001-1111 Input I1 unavailable for automatic selection. Input I1 priority value.
