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.
If set to ‘1’, the device will generate an interrupt when the buffer level crosses the
threshold set by the BUF bits. (see
If set to ‘1’, the device will generate an interrupt when the end of a conversion is
reached.
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.
