4.3.7.3
Mode E: In 8051 Multiplexed Bus Mode
In mode E: boot from HI08 in 8051 multiplexed bus mode, the bootstrap program sets
the host interface to interface with the Intel
Ò
8051 bus.
If the host processor sets host flag 0 (HF0) in the HCR while writing the initialization
program, the bootstrap program stops loading instructions, jumps to the starting
address specified, and executes the loaded program.
4.3.7.4
Mode F: In 68302/68360 Bus Mode
In mode F: boot from HI08 in 68302/68360 Bus mode, the bootstrap program sets the
host interface to interface with the Motorola 68302 or 68360 bus.
If the host processor sets host flag 0 (HF0) in the HCR while writing the initialization
program, the bootstrap program stops loading instructions, jumps to the starting
address specified, and executes the loaded program.
4.4
INTERRUPT SOURCES AND PRIORITIES
DSP56309 interrupt handling, like that of all DSP56300 family members, has been
optimized for DSP applications. Refer to
Section 7
of the
DSP56300
Family Manual.
The
interrupt table is located in the 256 locations of program memory to which the vector
base address (VBA) register in the program control unit (PCU) points.
4.4.1
Interrupt Sources
Each interrupt is allocated two instructions in the table, so there are 128 table entries for
interrupt handling.
shows the table entry address for each interrupt source.
