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.

0x00

TVTG-7

If TVTG-1 . . . 7 = 1, the signal will be DS1; otherwise, the

signal will be E1.

3TVTG-3

2TVTG-2

1TVTG-1

TOVERRIDE

If TOVERRIDE = 1, then the type of signal in each VT

Group is determined by the 7 TVTG bits.

0x89

—

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.

0x00

RVTG-7

If RVTG-1 . . . 7 = 1, the signal will be DS1; otherwise, the

signal will be E1.
