29.7.28
These registers reset to zero on a read and stick at all ones when they count to their maximum value. They should be read
frequently enough to prevent loss of data. The receive statistics registers are only incremented when the receive enable bit
is set in the network control register. To write to these registers, bit 7, WESTAT, in the network control register, NCR, must
be set. The statistics register block contains the following registers.
29.7.28.1
Register Name:
Access Type:
• FROK: Pause Frames received OK
A 16-bit register counting the number of good pause frames received. A good frame has a length of 64 to 1518 (1536 if bit
8, BIG, in network configuration register, NCFGR, is set, 10240 if bit 3, JFRAME in network configuration register, NCFGR,
is set) and has no FCS, alignment or receive symbol errors.
29.7.28.2
Register Name:
Access Type:
• FTOK: Frames Transmitted OK
A 24-bit register counting the number of frames successfully transmitted, i.e., no underrun and not too many retries.
