+-----------+-------+-------+---------+-------------+----------+
| Setting | AC LL | DC LL | ICC MAX | TDC Current | TDC Time |
| |(mOhms)|(mOhms)| (A) | (A) | (msec) |
+-----------+-------+-------+---------+-------------+----------+
| IA | 2.8 | 2.8 | 80 | 43 | 28000 |
+-----------+-------+-------+---------+-------------+----------+
| GT | 3.2 | 3.2 | 40 | 23 | 28000 |

- IA TDC current from 20A to 43A.
- GT TDC current from 20A to 23A.
BUG=b:256754175
TEST=Build test image and use PTAT to check IA and GT value
