ESP32 Forum

In the last TRM in the table of IO-MUX pin functions, there is no DAC1 and DAC2 function (they are missing). Later in description of IO MUX registers there are IO_MUX_GPIO17_REG and IO_MUX_GPIO18_REG with description

Configuration register for pad DAC_1

Configuration register for pad DAC_2

But which function index I have to populate in bit-field IO_MUX_MCU_SEL of those registers to route analog DACs output to GPIO17 and GPIO18 when they don't exist in IO MUX table in any of function columns?

Thanks for catching that. The ESP32-S3 does not have a DAC, and the pad descriptions are not correct; we'll fix those in the next TRM.
