Activation Sequence: I2S Bidirectional Capability
|
|
|
|
Between I2S writes at 0xE0817B and 0xE08590:
|
|
- 1050 bytes between events
|
|
- GPIO ops: 14 (SETB 0x34, CLR/SETB 0x32, 0x38, 0x2B, multiple toggles)
|
|
- Final: SETB 0x38 at 0xE08593 — activation before I2S bidirectional write
|
|
|
|
After I2S bidirectional:
|
|
- 4 GPIO ops within next 184 bytes
|
|
- CLR 0x38 at 0xE08641 (possible “deactivation/cleanup”)
|
|
Pattern:
|
|
1. Multiple GPIO toggles
|
|
2. SETB 0x38 [activation]
|
|
3. I2S bidirectional mode write
|
|
4. Operation executes
|
|
5. CLR 0x38 [cleanup]
|
|
6. Return to normal I2S mode
