Ausführliche Beschreibung

See xmega_pmic_quickstart.

This is a low-level driver implementation for the AVR XMEGA Programmable Multilevel Interrupt Controller.

Zu beachten
If these functions are used in interrupt service routines (ISRs), any non-ISR code or ISR code for lower level interrupts must ensure that the operations are atomic, i.e., by disabling interrupts during the function calls.

Dokumentation der Aufzählungstypen

enum pmic_level

Interrupt level bitmasks.

Zu beachten
These may be OR'ed, e.g., if multiple levels are to be enabled or disabled.
Aufzählungswerte
PMIC_LVL_LOW 

Low-level interrupts.

PMIC_LVL_MEDIUM 

Medium-level interrupts.

PMIC_LVL_HIGH 

High-level interrupts.

PMIC_LVL_NMI 

Non-maskable interrupts.

Zu beachten
These cannot be enabled nor disabled.

Definiert in Zeile 96 der Datei pmic.h.

enum pmic_schedule

Interrupt scheduling schemes.

Aufzählungswerte
PMIC_SCH_FIXED_PRIORITY 

Default, fixed priority scheduling.

PMIC_SCH_ROUND_ROBIN 

Round-robin scheduling.

PMIC_NR_OF_SCHEDULES 

Number of interrupt scheduling schemes.

Definiert in Zeile 115 der Datei pmic.h.

enum pmic_vector

Interrupt vector locations.

Aufzählungswerte
PMIC_VEC_APPLICATION 

Application section.

PMIC_VEC_BOOT 

Boot section.

PMIC_NR_OF_VECTORS 

Number of interrupt vector locations.

Definiert in Zeile 108 der Datei pmic.h.

Dokumentation der Funktionen

static void pmic_disable_level ( enum pmic_level  level)
inlinestatic

Disable interrupts with specified level(s).

Parameter
levelInterrupt level(s) to disable.

Definiert in Zeile 150 der Datei pmic.h.

static void pmic_enable_level ( enum pmic_level  level)
inlinestatic

Enable interrupts with specified level(s).

Parameter
levelInterrupt level(s) to enable.

Definiert in Zeile 138 der Datei pmic.h.

static enum pmic_level pmic_get_enabled_levels ( void  )
inlinestatic

Get currently enabled level(s)

Rückgabe
Bitmask with currently enabled levels.

Definiert in Zeile 176 der Datei pmic.h.

static void pmic_init ( void  )
inlinestatic

Initialize the PMIC.

Enables all interrupt levels, with vectors located in the application section and fixed priority scheduling.

Definiert in Zeile 127 der Datei pmic.h.

static bool pmic_level_is_enabled ( enum pmic_level  level)
inlinestatic

Check if specified interrupt level(s) is enabled.

Parameter
levelInterrupt level(s) to check.
Rückgabe
True if interrupt level(s) is enabled.

Definiert in Zeile 164 der Datei pmic.h.

static bool pmic_level_is_executing ( enum pmic_level  level)
inlinestatic

Check if an interrupt level(s) is currently executing.

Parameter
levelInterrupt level(s) to check.
Rückgabe
True if interrupt level(s) is currently executing.

Definiert in Zeile 189 der Datei pmic.h.

static void pmic_set_scheduling ( enum pmic_schedule  schedule)
inlinestatic

Set interrupt scheduling for low-level interrupts.

Parameter
scheduleInterrupt scheduling method to set.
Zu beachten
The low-priority vector, INTPRI, must be set to 0 when round-robin scheduling is disabled to return to default interrupt priority order.

Definiert in Zeile 202 der Datei pmic.h.

static void pmic_set_vector_location ( enum pmic_vector  vector)
inlinestatic

Set location of interrupt vectors.

Parameter
vectorLocation to use for interrupt vectors.

Definiert in Zeile 226 der Datei pmic.h.
