Function Documentation

§ CANCC27XX_getStatus()

uint32_t CANCC27XX_getStatus ( void )

Reads the CANCC27XX device status flags.

Returns: Device status flags.

See also: CANCC27XX_clearStatus

§ CANCC27XX_clearStatus()

void CANCC27XX_clearStatus ( void )

Clears all CANCC27XX device status flags.

See also: CANCC27XX_getStatus

§ CANCC27XX_setMode()

void CANCC27XX_setMode ( uint32_t mode )

Sets the CANCC27XX operational mode.

Parameters

mode	Operational mode to set: CANCC27XX_MODE_OPMODE_SLEEP, CANCC27XX_MODE_OPMODE_STANDBY, CANCC27XX_MODE_OPMODE_NORMAL

See also: CANCC27XX_getMode

§ CANCC27XX_getMode()

uint32_t CANCC27XX_getMode ( void )

Reads the CANCC27XX operational mode.

Returns: Operational mode: CANCC27XX_MODE_OPMODE_SLEEP, CANCC27XX_MODE_OPMODE_STANDBY, CANCC27XX_MODE_OPMODE_NORMAL

See also: CANCC27XX_setMode

§ CANCC27XX_disableSleepWakeErrorTimeout()

void CANCC27XX_disableSleepWakeErrorTimeout ( void )

Disables the sleep wake error timeout.

The sleep wake error timeout is enabled by default and powers down the CANCC27XX device within four minutes after power-on, reset, or coming out of sleep if the device is not configured by the host. This function can be used to disable the sleep wake error timeout and prevent the device from powering down.
