Function-[9:1]-AON and Function-[9:0] can all be output to PINX by setting pinx_pinmux_aon_sel and

pinx_pinmux_off_sel, as shown in Figure 2-12 below. Function-[9:1]-AON signals are part of

TOP_AON domain and Function-[9:0] signals are part of TOP_OFF (N9) domain. The output of the

pad is enabled through E and G pad controls which require 2’b11 for digital output mode.

For a specific pin there could be only a limited number of functions available, these functions are

mapped anywhere to the different inputs of the muxes (not always in an incremental scheme).

TOP_AON domain means the circuit is always powered on when PMU supplies the power. TOP_OFF

(N9) domain means the N9 related circuit is powered off in some scenarios when PMU supplies the

power.

Figure 2-13 below shows that PINX is the source of Function-AON-0, while PINX and PINY can both

be the input source for Function-1. The (E, G) setting for both IO is 2’b01 for digital input mode.
