Property 0x2300. TX_ASQ_INTERRUPT_SELECT
This property is used to enable which Audio Signal Quality (ASQ) measurements are returned by the
TX_ASQ_STATUS command. Overmodulation of the FM output signal due to excessive input signal level is
reported via the OVERMOD bit, which is enabled by setting the OVERMODIEN bit. A high or low input audio
condition is reported via the IALH and IALL bits which are enabled by the IALHIEN and IALLIEN bits. The CTS bit
(and optional interrupt) is set when it is safe to send the next command. This property may only be set or read
when in powerup mode.
