0x88
The bits in register 0x88 are used to override the DS1_E1N
signal pin. These bits represent the seven VT Groups and
can be individually programmed as follows.
If TVTG-1 . . . 7 = 1, the signal will be DS1; otherwise, the
signal will be E1.

TOVERRIDE
If TOVERRIDE = 1, then the type of signal in each VT
Group is determined by the 7 TVTG bits.
The bits in register 0x89 are used to override the DS1_E1N
signal pin. These bits represent the seven VT Groups and
can be individually programmed as follows.
If RVTG-1 . . . 7 = 1, the signal will be DS1; otherwise, the
signal will be E1.
