FIFO_
AUTORST
Automatic FIFO Overflow Reset
If this bit is set to "1", the STS-48 transceiver will automatically
flush the FIFO upon an overflow condition. Upon power-up, the
FIFO should be manually reset by setting FIFO_RST to "1" for a
minimum of 2 TXPCLKOP/N cycles.
"0" = Manual FIFO reset required for Overflow Conditions
"1" = Automatically resets FIFO upon Overflow Detection

FIFO_RST
Manual FIFO Reset
FIFORST should be set to "1" for a minimum of 2 TXPCLKOP/N
cycles during power-up and manual FIFO reset in order to flush out
the FIFO. After the FIFORST bit is returned "Low," it will take 8 to
10 TXPCLKOP/N cycles for the FIFO to flush out. Upon an inter-
rupt indication that the FIFO has an overflow condition, this bit is
used to reset or flush out the FIFO.
"0" = Normal Operation
"1" = Manual FIFO Reset

To automatically reset the FIFO, see the FIFO_AUTORST
bit.
