8.2 Configuration Registers
register is assigned a reference number for ease of location. The reference number may be used as a pointer to the
address of the register whenever the configuration address is being loaded or read. The registers are read or programmed

ERR_FAIL_TRIG
Hard wired bits that are set by the hard wired configuration of the device. These cannot be changed by
any programming method and are not affected by any of the resets. These bits may be read by any of the
designated methods for reading configuration registers. These primarily deal with port structure and
electrical connections. The shadow is the external pin.
Bits that will enter a default mode based upon the hard-wired configuration during Master Reset.
Subsequently these bits may be changed by any of the designated programming methods, and then
performing a “load configuration” reset. These primarily deal with internal device structure. These
registers must have a shadow register. Whenever a register containing RST bits are read by any of the
designated reading methods, the actual content of the register is returned and not the content of the
shadow register.
Bits that may be changed at any time without a Load Configuration reset. In the event JTAG or I
used to alter the content, a Load Configuration Reset must be performed. These primarily deal with data
routing and flagging. These registers have no shadow, except for the JTAG and I
may be read by any of the designated methods.
Read Only. Upon a master reset or load configuration, these will go to a known state, but once initialized
they are under control of the SerB internally. sRIO Transaction IDs are an example of a register that the

of this datasheet. The registers are shown with bit 0 assigned as the LSB of the
Reserved.
Error Rate Degraded Threshold Trigger:
These bits provide the threshold value for reporting an error condi-
tion due to a degrading link.
0x00 - Disable the Error Rate Degraded Threshold Trigger
0x01 - Set the error reporting threshold to 1
0x02 - Set the error reporting threshold to 2
...
0xFF - Set the error reporting threshold to 255.
Error Rate Failed Threshold Trigger:
These bits provide the threshold value for reporting an error condi-
tion due to a possibly broken link:
0x00 - Disable the Error Rate Failed Threshold Trigger
0x01 - Set the error reporting threshold to 1
0x02 - Set the error reporting threshold to 2
...
0xFF - Set the error reporting threshold to 255.
