6.3.3 Statistics Register Definitions

Statistics registers accumulate statistics for software drivers, RMON applications, and
other uses. Reading statistics registers resets the counts to zero. If they are not read
before reaching maximum count, the count does not wrap, but sticks at all 1s. The receive
statistics registers only increment when the NETCTL:RXEN is programmed to 1.
For testing purposes, the statistics registers can be written to. Before writing to the statis-
tics registers, NETCTL:WRENSTAT must first be programmed to 1.
6.3.3.1 Pause Frames Received (PAUSEFRRX)
This register allows software to read the number of good pause frames received. A good
frame has a length of 64 to 1,518 (1,522 if NETCONFIG:RECBYTE is 1) and has no FCS,
alignment or receive symbol errors.
