Tool/software:
We are using the **TPS546D24S** to achieve an **80A output** by **stacking two devices in a 2-phase configuration**.
We have configured the hardware according to the recommended reference design (as shown in the attached schematic).
For PMBus communication, we modified the following registers:
---
### 
Interleaving Configuration
- **Controller:**
- `INTERLEAVE` = `0x0020` (0° phase shift)
- **Follower:**
- `INTERLEAVE` = `0x0021` (180° phase shift)
- `NUM_PHASES` (NUM_GRP) = `2` (2 phases total)
- `PHASE_ORDER` = `0` (Controller), `1` (Follower)
---
### Stack Configuration
- **Controller:** `STACK_CONFIG` = `0x00 0x01` (1 follower, 2-phase)
- **Follower:** No configuration required
---
### SYNC Configuration
- **Controller:** `SYNC_CONFIG` = `0xF0` (Auto-detect SYNC OUT)
- **Follower:** `SYNC_CONFIG` = `0xB0` (SYNC IN)
---
### 
Issue
After applying these settings, we are encountering a **BCX error**.
We would appreciate any insights or suggestions for resolving this issue.
