inb (3avr)

This header file contains several items that used to be available in previous versions of this library, but have eventually been deprecated over time.

#include <compat/deprecated.h>

These items are supplied within that header file for backward compatibility reasons only, so old source code that has been written for previous library versions could easily be maintained until its end-of-life. Use of any of these items in new code is strongly discouraged.

#define cbi(port, bit) (port) &= ~(1 << (bit))

Deprecated

Clear bit in IO port port.

#define enable_external_int(mask) (__EICR = mask)

Deprecated

This macro gives access to the GIMSK register (or EIMSK register if using an AVR Mega device or GICR register for others). Although this macro is essentially the same as assigning to the register, it does adapt slightly to the type of device being used. This macro is unavailable if none of the registers listed above are defined.

#define inb(port) (port)

Deprecated

Read a value from an IO port port.

#define inp(port) (port)

Deprecated

Read a value from an IO port port.

#define INTERRUPT(signame)

Value:

void signame (void) __attribute__ ((interrupt,__INTR_ATTRS));       void signame (void)

Deprecated

Introduces an interrupt handler function that runs with global interrupts initially enabled. This allows interrupt handlers to be interrupted.

As this macro has been used by too many unsuspecting people in the past, it has been deprecated, and will be removed in a future version of the library. Users who want to legitimately re-enable interrupts in their interrupt handlers as quickly as possible are encouraged to explicitly declare their handlers as described above.

#define outb(port, val) (port) = (val)

Deprecated

Write val to IO port port.

#define outp(val, port) (port) = (val)

Deprecated

Write val to IO port port.

#define sbi(port, bit) (port) |= (1 << (bit))

Deprecated

Set bit in IO port port.

static __inline__ void timer_enable_int (unsigned charints)\fC [static]\fP

Deprecated

This function modifies the \c timsk register.
The value you pass via \c ints is device specific.  .fi
