6.7 Test Pattern Generator and Monitor Registers
Table 6-35. TPG_Configuration (Read/Write)
The TPG can be configured to generate any one of the ITU-T test patterns specified in O.150, O.151, or O.152, as well as
idle code or user-specified data.

TPG_Pattern_Invert. Data output patterns are inverted when this bit is selected.
0 = Do not invert TPG data.
1 = Invert TPG data.
Enable_Error_Exercise. This works in conjunction with both the TPG_Inject_Error_Count
(see
bit register that allows for bit-wise XORing of the data output. The former gets loaded with
the number of N-bit errors that will be generated with N being the number bits set in the
Data_Invert_Mask. If the Data_Invert_Mask is set to 0x00, then no errors will be injected
despite the fact the TPG_Inject_Error_Count register will continue to decrement.
0 = Disable error exercising.
1 = Enable error exercise option.
Pattern_Generator_Enable. Enable the pattern generator:
0 = Pattern generator off.
1 = Pattern generator on.
Note: Setting this bit to 0 will not reset the TPM_Error_Count (see
TPG_Pattern_Select. These bits select the test pattern to be generated and inserted into
the selected time slots. Changing the pattern will reset the TPM_Error_Count register (see
