4.34 Diagnostic Register
The diagnostic register is provided for internal TI test purposes. It is a read/write register, but only 0s should be written
to it. See Table 4
13 for a complete description of the register contents.

TRUE_VAL
RW
This bit defaults to 0. This bit is encoded as:
0 = Reads true values in PCI vendor ID and PCI device ID registers (default)
1 = Reads all 1s in reads from the PCI vendor ID and PCI device ID registers
6
RSVD
R
Reserved. Bit 6 returns 1 when read.
5
CSC
RW
CSC interrupt routing control
0 = CSC interrupts routed to PCI if ExCA 803 bit 4 = 1
1 = CSC interrupts routed to PCI if ExCA 805 bits 7
4 = 0000b (default)
In this case, the setting of ExCA 803 bit 4 is a don
t care.

DIAG4
RW
Diagnostic RETRY_DIS. Delayed transaction disable.
DIAG3
RW
Diagnostic RETRY_EXT. Extends the latency from 16 to 64.
Diagnostic DISCARD_TIM_SEL_CB. Set = 210, reset = 215.
Diagnostic DISCARD_TIM_SEL_PCI. Set = 210, reset = 215.

STDZVEN
RW
Standardized zoomed video register model enable.
0 = Enable the standardized zoomed video register model (default).
1 = Disable the standardized zoomed video register model.
This bit is global and is accessed only through function 0.
