Table 6-40. TPG_Inject_Error_Count (Write Only)
This register provides a mask for specifying which bits of TPG data are to be inverted when forcing errors.

The TPM_Error_Count register can be reset in one of the following four ways:
1. The pattern is changed.
2. The bit RESET_TPM_Error_Counter (in the TPM_Configuration register, see
