3.4.5.4
Configuration 4 - GPIO Mode (Reserved)
When the CFG_STRAP is configured to this mode, the programmable function pins (PROG_FUNC[7:1]) are set to pro-
vide 7 general purpose I/Os that can be used for GPIO bridging. Table 3-19 details the PROG_FUNC[7:1] pin assign-
ments in this mode.
3.4.5.5
Configuration 5 - Battery Charging / Power Delivery Indicator Mode
When the CFG_STRAP is configured to this mode, the programmable function pins (PROG_FUNC[7:1]) are set to indi-
cate battery charging and 3 general purpose I/Os. Table 3-20 details the PROG_FUNC[7:1] pin assignments in this
mode.
