+# Error handling ################################################################
+
+config CONFIG_ERRORS
+	bool "Errors support"
+	default y
+	---help---
+	This enables error handling. This enables some checks and allows both avr-ioe
+	and you program to react on errors. This doesn't handless hardware errors,
+	only software ones.

+config CONFIG_EH_RESTART
+	bool "Restart MCU on error detection"
+	default n
+	---help---
+	CPU is restarted when error is detected. This is suggested in production.
+
+config CONFIG_EH_HANG
+	bool "Hang execution until manual restart on error detection"
+	default n
+	---help---
+	Program hangs execution when error is detected. This is suggested in
+	development.
+
+config CONFIG_EH_LED
+	bool "Signal error detection by LED"
+	depends on CONFIG_IOPORTS
+	default n
+	---help---
+	When error is detected, specified output is pulled up. This is handy with
+	CONFIG_EH_HANG. If you use this with CONFIG_EH_RESTART you will probably
+	miss led blink.
+
+config CONFIG_EH_LED_IOPIN
+	string "Error detection led output pin"
+	depends on CONFIG_EH_LED
+	default "IO_B0"
+	---help---
+	Specifies IO pin which will be pulled up on error detection.
+	This string should be valid IO port (for example "IO_B0") or pair of group
+	mask divided by comma (for example "IO_B, _BV(0)").

+config CONFIG_ERROR_MESSAGES
+	bool "Build with error messages"
+	default n
+	---help---
+	If errors should support messages. Compiling error messages to code can be
+	handy to finding out errors, but also makes program unnecessary big.
+
+config CONFIG_ERROR_CALLBACK
+	bool "User program implements callback to be used to optionally resolve error"
+	default n
+	---help---
+	This allows user program to define error callback to be called just after
+	error is detected. This also can suppress error, but that is dangerous and
+	should be used only with deep understanding of what it means.
+
+config CONFIG_CHECK_ARGUMENTS
+	bool "Check arguments for all functions in library"
+	default n
+	---help---
+	If arguments passed to functions in library should be checked and
+	possibly error should be risen.
