The bits of each register are described below:

COM Register

ICNT

If set to a ‘1’, the device will generate an interrupt when the Count register has

been updated. This occurs after each word has been spoken.

IBUF

If set to ‘1’, the device will generate an interrupt when the buffer level crosses the

threshold set by the BUF bits. (see Table 3, Status bytes).

ICNV

If set to ‘1’, the device will generate an interrupt when the end of a conversion is

reached.

BUF1..0

If IBUF is set, BUF1..0 determines the buffer level at which the interrupt will be

generated.

00b – Input buffer empty.

01b – Input buffer <10% full.

10b – Input buffer <50% full.

11b – Input buffer <75% full.
