View Ref-FileHost Flag 2 (HF2) HCR Bit 3:

    The HF2 bit is used as a general-purpose flag for DSP-to-host
communication. HF2 may be set or cleared by the DSP. HF2 is visible in the
interrupt status register (ISR) on the host processor side. Hardware and
software resets clear HF2.

NOTE:   There are four host flags: two used by the host to signal the DSP
(HF0) and (HF1) and two used by the DSP to signal the host processor (HF2) and
(HF3).These flags are not designated for any specific purpose but are
general-purpose flags. The host flags do not cause interrupts; they must be
polled to see if they have changed. These flagscan be used individually or
as encoded pairs.
