Byte
If an interrupt has occurred, no further interrupts will be registered until the first interrupt has been
cleared. Only one interrupt can be active at any time.
The RINT command will read and clear pending interrupts while the RDST command will read
interrupts without clearing them.
Make sure that all interrupts that are not being used are masked by clearing the corresponding bits in
the COM register.
*5 bits are reserved.

Ready to accept commands. After the device has been powered up,
this bit is set after the Power Up latency delay.
Converting. This bit is set anytime while the conversion process is
running. If this bit is clear when a convert command is sent, the count in
the Count register is set to 0.
empty.
The text input buffer is full. This bit is cleared after 128 bytes become
available in the input buffer.
CODEC is enabled. This is set when the CODEC has been enabled by
the SCOD command.
Conversion finished interrupt has occurred. To stop CODEC
transmission or Power Down the analog outputs an IDLE command
should be sent. This bit is cleared by RINT command.
The input text buffer been filled above the defined threshold and then
gone below the defined threshold. The buffer threshold level is set by
the SCOM command. If set by the SCOM command, the INT pin will
also go LOW. This bit is cleared by RINT command.
Count interrupt has occurred. This interrupt is generated every time a
word has been spoken if activated by the SCOM command. This bit is
cleared by RINT command.
Command was ignored. Anytime ICMD is set, the transaction must
revert to a single word command and the command must be resent.
Any data sent will be ignored.
delete has been completed. Now the ENTER_RRSM command can be
sent.
Current state of the R/ B pin. If this bit is 0, any data sent will be
ignored.
The text input buffer is empty. This bit is set anytime the input buffer is
Abbreviation interrupt has occurred, abbreviation add or abbreviation
