Remote Configuration Registers
Remote Configuration Registers
The remote configuration registers listed in
Table 24
are the same registers as previously described, but
they are for the remote VLYNQ device.
Note:
Before attempting to access the remote registers (offsets 80h through C0h) , you must
ensure that a link is established with the remote device. Poll the LINK bit in the VLYNQ
status register (STAT) to do this.
It is not necessary to configure the address translation registers to access the remote
device's memory-mapped registers after the link has been established.
Depending on the version and chip specific implementation, the VLYNQ module on the
remote device might have additional registers or different reset values. Refer to the remote
device data sheet for a precise description of the VLYNQ registers that exist in the remote
device.
