3 Pin Definitions Table 2 – cont’d from previous page 1 Name No.
3 Pin Definitions • GPIO5 Software can read the values of these five bits from register ”GPIO_STRAPPING”. During the chip’s system reset release (power-on-reset, RTC watchdog reset and brownout reset), the latches of the strapping pins sample the voltage level as strapping bits of ”0” or ”1”, and hold these bits until the chip is powered down or shut down. The strapping bits configure the device’s boot mode, the operating voltage of VDD_SDIO and other initial system settings.
