7.2.4
These two registers share the same address. In all Register Sets, Set Select Register (SSR) can be
programmed to select a desired Set, but IR Control Register can only be programmed in Set 0 and
Set 1. In other words, writing to Reg3 in Sets other than Set 0 and Set 1 will not affect IR Control
Register. The mapping of entry Set and programming value is shown below.
