Host Interface (HI08)
HI08 DSP Side ProgrammerÕs Model
6.5.5
Host Base Address Register (HBAR)
The HBAR is used in multiplexed bus modes. This register, illustrated in
selects the base address where the host side registers are mapped into the bus address
space. The address from the host bus is compared with the base address as programmed
in the base address register. If the addresses match, an internal chip select is generated.
The use of this register by the chip select logic is described in
6.5.5.1
HBAR Base Address (BA[10:3]) Bits 0-7
These bits reflect the base address where the host-side registers are mapped into the bus
address space.
6.5.5.2
HBAR Reserved Bits 8-15
These bits are reserved. They are read as 0 and should be written with 0.
6.5.6
Host Port Control Register (HPCR)
The HPCR is a 16-bit, read/write control register by which the DSP controls the HI08
operating mode. Reserved bits are read as 0 and should be written with 0 for future
compatibility. The initialization values for the HPCR bits are described in
Section 6.5.9ÑDSP Side Registers After Reset
. The HPCR bits are illustrated in
