Description

SRC_BUF

Output data buffer status event flag

0: No output buffer event status flags are active

1: One or more output buffer status event flags are active (BUF_WMRK | BUF_OVF |

BUF_GATE_ERR); reading the

BUF_STATUS register provides more information on the BUF_WMRK

or BUF_OVF event flags that are currently active. Reading the

SYS_MODE register provides

information on the BUF_GATE_ERR flag status.

Notes:

• The SRC_BUF flag is only active when BUF_CONFIG1[BUF_MODE[1:0]] > 00b.

• The BUF_WMRK event flag will not participate in SRC_BUF interrupt generation in triggered mode

(the BUF_WMRK flag is asserted after the buffer is triggered, but it will not signal an external

interrupt as with the other buffer operating modes). If it is required to know when the trigger event

has taken place, the host may use the SDCD or ORIENT interrupts, as appropriate, to indicate

when the buffer is triggered. When the buffer is full, the SRC_BUF flag is set and an external

interrupt is signaled on the INT1 or INT2 pins, if configured.

SRC_SDCD_OT

SDCD outside of thresholds condition event flag (copy of

SDCD_INT_SRC1[OT_EA] flag)

0: SDCD outside of thresholds event is not detected (

SDCD_INT_SRC1[OT_EA] = 0).

1: SDCD outside of thresholds event is detected (

SDCD_INT_SRC1[OT_EA] = 1). The

SRC_SDCD_OT event flag is cleared by reading the

SDCD_INT_SRC1 register when SDCD_

CONFIG1[OT_ELE] = 1, otherwise this flag is cleared automatically by the function when the event

condition becomes false.

SRC_SDCD_WT

SDCD within thresholds condition event flag (copy of

SDCD_INT_SRC2[WT_EA] flag)

0: No SDCD within thresholds event has been detected (

SDCD_INT_SRC2[WT_EA] = 0).

1: An SDCD within thresholds event has been detected (

SDCD_INT_SRC2[WT_EA] = 1). The

SRC_SDCD_WT event flag is cleared by reading the

SDCD_INT_SRC2 register when SDCD_

CONFIG1[WT_ELE] = 1, otherwise the function clears this flag automatically when the event

condition becomes false.

SRC_ORIENT

Orientation change event flag

The SRC_ORIENT flag is asserted whenever the

ORIENT_STATUS[NEW_ORIENT] bit is asserted

and a change in orientation has been detected.

Reading the

ORIENT_STATUS register clears this event flag.

0: An orientation change event has not occurred

1: An orientation change event has occurred.
