Recovery:

// Emergency system recovery - reset all communication peripherals
reset_controller.assert_reset(Control::LPUART0);
reset_controller.assert_reset(Control::LPUART1);
reset_controller.assert_reset(Control::LPI2C0);
reset_controller.assert_reset(Control::LPSPI0);
// Wait for system stabilization
system_delay(reset_recovery_time);
// Release resets in proper sequence
reset_controller.release_reset(Control::LPI2C0);
reset_controller.release_reset(Control::LPSPI0);
reset_controller.release_reset(Control::LPUART0);

Power Management Integration:

• Reset assertion automatically gates peripheral clocks for power saving
• Use reset control for dynamic power management in low-power applications
• Some peripherals may retain state in certain low-power modes even when reset
• Coordinate reset control with clock management and power mode transitions

Debug Considerations:

• Reset state affects peripheral register visibility in debug tools
• Some debug interfaces may become unavailable when communication peripherals are reset
• Consider debug requirements when implementing reset sequences in production code
