PTR[8]

PTR[9:8]:

The PTR[9:8] bits contain the two MSBs of the current pointer value that is

interpreted from the H1 and H2 bytes. The NDFI, NSEI and PSEI bits of the

RPOP Pointer Interrupt Status register should be read before and after

reading this register to ensure that the pointer value did not change during

the register read.

S0, S1:

The S0 and S1 bits contain the two S bits received in the last H1 byte. These

bits should be software debounced by reading this register at least twice.

RDI10:

The RDI10 bit controls the filtering of the remote defect indication and the

auxiliary remote defect indication. When RDI10 is a logic one, the PRDI and

APRDI status is updated when the same value is received in the

corresponding bit of the G1 byte for ten consecutive frames. When RDI10 is

a logic zero, the PRDI and APRDI status is updated when the same value is

received for five consecutive frames.
