Host Write Strobe, Host Data Strobe, General Purpose I/O
In Intel parallel host mode, this pin serves as the active-low data bus enable input. In Motorola
parallel host mode, this pin serves as the read-high/write-low control input signal. In serial host
mode, this pin can serve as a general purpose input or output bit. This pin can act as a
general-purpose input or output that can be individually configured and controlled by DSP C.
CS, GPIO9 — Host Parallel Chip Select, General Purpose I/O
In parallel host mode, this pin serves as the active-low chip-select input signal. This pin can
act as a general-purpose input or output that can be individually configured and controlled by
DSP C.
HINBSY, GPIO8 — Input Host Message Status, General Purpose I/O
This pin indicates that serial or parallel communication data written to the DSP has not been
read yet. This pin can act as a general-purpose input or output that can be individually
configured and controlled by DSP C.
