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.
