📖 Notes:
•
INST_NAME refers to the IO_MUX REGISTER defined in eagle_soc.h, for example MTDI_U refers to
PERIPHS_IO_MUX_MTDI_U.
• Net Name refers to the pin name in schematic.
• Function refers to the multifunction of each pin pad.
• Function number 1 ~ 5 correspond to FUNCTION 0 ~ 4 in SDK. For example, set MTDI to GPIO12 as
follows.
- #define󰲧FUNC_GPIO12󰲧󰲧3󰲧//defined󰲧in󰲧eagle_soc.h
- PIN_FUNC_SELECT(PERIPHS_IO_MUX_MTDI_U,FUNC_GPIO12)
