Notes For Tables 4 And 5:
1.
PTR = Polynomial Tap Register (address = 05)
2.
PLR = Pattern Length Register (address = 04)
3.
PSR3 = Pattern Set Register 3 (address = 00)
4.
PSR2 = Pattern Set Register 2 (address = 01)
5.
PSR1 = Pattern Set Register 1 (address = 02)
6.
PSR0 = Pattern Set Register 0 (address = 03)
7.
TINV = Transmit Data Inversion Select Bit (EIR.5)
8.
RINV = Receive Data Inversion Select Bit (EIR.4)
9.
For the 2
32
-1 pattern, the random pattern actually repeats every (4093 x 2
20
) + 1046529 bits instead of
2
32
- 1.
8.
The Bit Count Registers (BCR3 to BCR0) comprise a 32-bit count of bits (actually RCLK cycles)
received at RDATA. BC31 is the MSB of the 32-bit count. The bit counter increments for each cycle of
RCLK when input pin RDIS is low. The bit counter is disabled during loss of SYNC. The Status Register
bit BCOF is set when this 32-bit register overflows. Upon an overflow condition, the user must clear the
BCR by either toggling the LC bit or pin. The DS21372 latches the bit count into the BCR registers and
clears the internal bit count when either the PCR.4 bit or the LC input pin toggles from low to high. The
bit count and bit error count (available via the BECRs) are used by an external processor to compute the
BER performance on a loop or channel basis.
