Description
8
tx_buf_
resync
RW 1'b0 Force transmit buffer pointer resynchronization. You can use
this register field to resynchronize if, for example, the buffer fill
level becomes too high due to due to environmental impacts on
the device, such as temperature. Resynchronizing might lead to
data loss or corruption.
Do not use this register field to resynchronize after a dynamic
CPRI line bit rate change. After a dynamic CPRI line bit rate
change the IP core forces resynchronization internally without
referring to this register.
