Bit Description
Reserved for future use. Returns undefined value when read.
CPRI loss of signal (LOS) status. A value [1] indicates loss of frame.
Loss of signal count. The maximum count which can be accumulated in
this register is 8'hFF.
Bit Description
Reserved for future use. Returns undefined value when read.
Deserializer PLL loss of lock count since the last read operation of this
register. The maximum count which can be accumulated in this register
is 8'hFF.
Note: During normal operation, receive PLL can go through multiple
locking cycles before finally declaring lock. This is normal behavior.
Bit Description
SPMODE[1:0] pin status

RXPWDNB pin status
A value [1] indicates local loopback is enabled
A value [1] indicates line loopback is enabled
A value [1] indicates special local loopback is enabled
A value [1] indicates special line loopback is enabled
A value [1] indicates digital loopback is enabled
Inverted value of RXCLKMODE pin.
Reserved for future use. Returns undefined value when read.
This register bit indicates a loss of TXCLK. A value of 1 indicates the
TXCLK is not present or not running in the currently programmed speed
mode.
This register bit indicates a loss of RXCLK. A value of 1 indicates the
RXCLK is not present or not running in the currently programmed speed
mode. The RXCLK feature is only supported in SCAN12100 READ
mode operation.
