PTRV[9:0]:
The path pointer value (PTRV[9:0]) bits represent the current STS (AU or TU3) pointer being
process by the pointer interpreter state machine or by the concatenation pointer interpreter
state machine.
SSV[1:0]:
The SS value (SSV[1:0]) bits represent the current SS (DD) bits being processed by the
pointer interpreter state machine or by the concatenation pointer interpreter state machine.
PERDIV[2:0]:
The path enhanced remote defect indication value (PERDIV[2:0]) bits represent the filtered
path enhanced remote defect indication value. PERDIV[2:0] is updated when the same ERDI
pattern is detected in bits 5,6,7 of the G1 byte for five or ten consecutive frames (selectable
with the PRDI10 register bit).
These bits are only valid for RHPP STS-1/STM0 #1.
