PS:

The PS bit selects the generated pattern. When PS is a logic 1, a repetitive

pattern is generated. When PS is a logic 0, a pseudo-random pattern is

generated.

The PS bit must be programmed to the desired setting before programming

any other PRGD registers, or the transmitted pattern may be corrupted. Any

time the setting of the PS bit is changed, the rest of the PRGD registers

should be reprogrammed.

TINV:

The TINV bit controls the logical inversion of the generated data stream.

When TINV is a logic 1, the data is inverted. When TINV is a logic 0, the data

is not inverted

RINV:

The RINV bit controls the logical inversion of the receive data stream before

processing. When RINV is a logic 1, the received data is inverted before

being processed by the pattern detector. When RINV is a logic 0, the

received data is not inverted

AUTOSYNC:

The AUTOSYNC bit enables the automatic resynchronization of the pattern

detector. The automatic resynchronization is activated when 6 or more bit

errors are detected in the last 64 bit periods. When AUTOSYNC is a logic 1,

the auto resync feature is enabled. When AUTO SYNC is a logic 0, the auto

sync feature is disabled, and pattern resynchronization is accomplished using

the MANSYNC bit.

MANSYNC:

The MANSYNC bit is used to initiate a manual resynchronization of the

pattern detector. A low to high transition on MANSYNC initiates the

resynchronization.
