PD[31:0]

PD[31:0] contain the pattern detector data. The values contained in these registers are

determined by the PDR[1:0] bits in the control register.

When PDR[1:0] is set to 00 or 01, PD[31:0] contain the pattern receive register. The 32 bits

received immediately before the last accumulation interval are present on PD[31:0}. PD[31]

contains the first of the 32 received bits, PD[0] contains the last of the 32 received bits.

When PDR[1:0] is set to 10, PD[31:0] contain the error counter holding register. The value in

this register represents the number of bit errors that have been accumulated since the last

accumulation interval. Note: Bit errors are not accumulated while the pattern detector is out-

of-sync.

When PDR[1:0] is set to 11, PD[31:0] contain the bit counter holding register. The value in

this register represents the total number of bits that have been received since the last

accumulation interval.

The values of PD[31:0] are updated whenever one of the four PRGD Pattern Detector

Registers is written or when Register 006H, the S/UNI-JET Identification, Master Reset, and

Global Monitor Update Register is written.
