This graph shows which files directly or indirectly include this file:

Internal flag which defines if uart state is stored on SRAM
#define	AVR8_STATE_UART_USE_SRAM 1
	UART state using SRAM.

UART TX pending state

Note: The content must be changed using the pair avr8_uart_tx_set_pending and avr8_uart_tx_clear_pending methods and the state is stored on avr8_state_uart.

Label	Description
TX7	This bit is set when on UART7 TX is pending
TX6	This bit is set when on UART6 TX is pending
TX5	This bit is set when on UART5 TX is pending
TX4	This bit is set when on UART4 TX is pending
TX3	This bit is set when on UART3 TX is pending
TX2	This bit is set when on UART2 TX is pending
TX1	This bit is set when on UART1 TX is pending
TX0	This bit is set when on UART0 TX is pending

#define avr8_state_uart GPIOR0

Definition for GPIOR0.

Internal flag which defines if IRQ state is stored on SRAM
#define	AVR8_STATE_IRQ_USE_SRAM 1
	IRQ state using GPIOR registers.

Global variable containing the current state of the MCU

Note: This variable is updated from IRQ context; access to it should be wrapped into irq_disable and irq_restore should be used.

Label	Description
IRQ	This variable is incremented when in IRQ context
