(1). Special function capture pin, the module will detect the status of these pins when starting up and
enter special functions, please refer to chapter 3.2.3
(2). The default state of the pin. When the Reset button is pressed, all GPIO ports will remain in their
previous state. When the Reset button is released, the GPIO state returns to the state described in
"Default State" in Table 1, where EfusePullCtrlx indicates that the default state of the pin is the status bits
in eFuse are determined.
(3). The time from system power-up to GPIO power supply can be divided into three phases:
⚫ The supply voltage rises to 1.5V and the internal AON_LDO voltage rises to 0.5V. Determined
by 3.3V/1.8V power-on time
⚫ The internal analog circuit of the chip needs 6ms to supply power to the Reset button, and
then the digital circuit starts to work.
⚫ After 300us~1.5ms, the general GPIO is powered, the default level will take effect.
⚫ Phase 2 and Phase 3 require a total of 6.3ms ~ 7.5ms
3.2.2. Low Power Pin Definition
Low-power pins can wake the module from the Deep Sleep state and are located on the keyboard scan
function pin.
Table 2 Low Power Pin Definition
3.2.3. Special Function Capture Pins
The status of these pins is detected during power-up of the module, allowing access to certain special
modes and functions. These features are hardware determined and cannot be modified.
