GPIO 0 Reset Control.

GPIO 0 Reset ControlControls reset state of the General Purpose Input/Output 0 (GPIO0) controller. GPIO0 provides direct digital I/O control for the first bank of GPIO pins.

通用輸入輸出 0 重置控制，第一組GPIO直接數位控制

GPIO0 Functions:

• Digital input and output control
• Individual pin direction and state control
• Input/output data register management
• Pin state reading and writing

註

Reset Effects:

• All GPIO pins configured as inputs (high impedance)
• Output data registers cleared to 0

• Direction registers reset to input mode

  Initialization:

  // Initialize GPIO0 for digital I/O
  reset_ctrl.assert_reset(Control::GPIO0);
  reset_ctrl.release_reset(Control::GPIO0);
  gpio0_configure_pins(pin_mask, directions);
