ZHCSAU2G September 2012 – June 2018 SN65DSI84
PRODUCTION DATA.
Use the following initialization sequence to setup the SN65DSI84. This sequence is required for proper operation of the device. Steps 9 through 11 in the sequence are optional.
Also see to Figure 6.
| INITIALIZATION SEQUENCE NUMBER | INITIALIZATION SEQUENCE DESCRIPTION |
|---|---|
| Init seq 1 | Power on |
| Init seq 2 | After power is applied and stable, the DSI CLK lanes MUST be in HS state and the DSI data lanes MUST be driven to LP11 state |
| Init seq 3 | Set EN pin to Low |
| Wait 10 ms (1) | |
| Init seq 4 | Tie EN pin to High |
| Wait 10 ms (1) | |
| Init seq 5 | Initialize all CSR registers to their appropriate values based on the implementation (The SN65DSI8x is not functional until the CSR registers are initialized) |
| Init seq 6 | Set the PLL_EN bit (CSR 0x0D.0) |
| Wait 10 ms (1) | |
| Init seq 7 | Set the SOFT_RESET bit (CSR 0x09.0) |
| Wait 10 ms (1) | |
| Init seq 8 | Change DSI data lanes to HS state and start DSI video stream |
| Wait 5 ms (1) | |
| Init seq 9 | Read back all resisters and confirm they were correctly written |
| Init seq 10 | Write 0xFF to CSR 0xE5 to clear the error registers |
| Wait 1 ms (1) | |
| Init seq 11 | Read CSR 0xE5. If CSR 0xE5!= 0x00, then go back to step #2 and re-initialize |
