Framer Register Architecture
Reserved Parameter/Control Registers
Registers FRM_PR67 and FRM_PR68, addresses 6A3 and 6A4 or CA3 and CA4, are reserved. Write these regis-
ters to 0.
Auxiliary Pattern Generator Control Register (FRM_PR69)
The following register programs the auxiliary pattern generator in the transmit framer. The default value of this reg-
ister is 00 (hex).
Table 160. Auxiliary Pattern Generator Control Register (FRM_PR69) (YA5)*
* To generate test pattern signals using this register, register FRM_PR20 must be set to 00 (hex).

Invert Transmit Data. Setting this bit to 1 inverts the transmitted pattern.
Test Pattern Error Insertion. Toggling this bit from a 0 to a 1 inserts a single bit error in
the transmitted test pattern.
Generator Block Select. Setting this bit to 1 enables the generation of test patterns in
this register.
Generator Frame Test Pattern. Setting this bit to 1 results in the generation of an
unframed pattern. A 0 results in a framed pattern (T1 and CEPT).
Generator Pattern Select. These 4 bits select which random pattern is to be
transmitted.
