DSP56309UM/D MOTOROLA
Host Interface (HI08)
HI08-External Host ProgrammerÕs Model
6.6.7
Host Side Registers After Reset
shows the result of the four kinds of reset on bits in each of the HI08 registers
seen by the host processor. The hardware reset is caused by asserting the RESET signal.
The software reset is caused by executing the RESET instruction. The individual reset is
caused by clearing the HEN bit in the HPCR. The stop reset is caused by executing the
STOP instruction.
6.6.8
General-Purpose I/O
When configured as GPIO, the HI08 is viewed by the DSP56309 as memory-mapped
registers, as documented in
Section 6.5ÑHI08 DSP Side ProgrammerÕs Model
page 6-8. Those memory-mapped registers control up to 16 I/O signals. Software RESET
instructions and hardware RESET signals clear all DSP side control registers and
configure the HI08 as GPIO with all 16 signals disconnected. External circuitry
