Function Documentation

§ TCAN455X_getStatus()

uint32_t TCAN455X_getStatus ( void )

Reads the TCAN455X device status flags.

Returns: Device status flags.

See also: TCAN455X_clearStatus

§ TCAN455X_clearStatus()

void TCAN455X_clearStatus ( void )

Clears all TCAN455X device status flags.

See also: TCAN455X_getStatus

§ TCAN455X_setMode()

void TCAN455X_setMode ( uint32_t mode )

Sets the TCAN455X operational mode.

Parameters

mode	Operational mode to set: TCAN455X_MODE_OPMODE_SLEEP, TCAN455X_MODE_OPMODE_STANDBY, TCAN455X_MODE_OPMODE_NORMAL

See also: TCAN455X_getMode

§ TCAN455X_getMode()

uint32_t TCAN455X_getMode ( void )

Reads the TCAN455X operational mode.

Returns: Operational mode: TCAN455X_MODE_OPMODE_SLEEP, TCAN455X_MODE_OPMODE_STANDBY, TCAN455X_MODE_OPMODE_NORMAL

See also: TCAN455X_setMode

§ TCAN455X_disableSleepWakeErrorTimeout()

void TCAN455X_disableSleepWakeErrorTimeout ( void )

Disables the sleep wake error timeout.

The sleep wake error timeout is enabled by default and powers down the TCAN455X 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.
