ADSP-2192 Peripheral Device Control Registers
B-58 ADSP-219x/2192 DSP Hardware Reference
PCI Configuration Register Space, Function 1
PCI Configuration Spaces should be accessed only by the DSP, and only
during the boot process. After the PCI interface has been configured, bit 2
of the
PCI_CFGCTL
register (
ConfRdy
) should be set by the DSP. This allows
the PCI interface access to these registers while at the same time denying
the DSP access.
L
Access to these registers is controlled by the PCI RDY bit in the
Chip Mode/Status Register (Page 0x00, Address 0x00). See
“ADSP-2192 Chip Control Registers” on page B-13
.
