| 31:1 | CANUART_WAKE_CTRL_MW | R/W | 0h | CANUART IO magic word. This 31-bit value that activates placing of the CANUART I/Os into isolation for daisy-chain wakeup operation. 0x2AAAAAAA - Magic word value to activate isolation whenqualified with mw_load bit Others - Any other value will prevent isolation when mw_loadtransitions from 0 to 1 Reset Source: mcu_chip1_rst_n |
| 0 | CANUART_WAKE_CTRL_MW_LOAD_EN | R/W | 0h | Magic word load activate Setting this bit to 1 loads and locks the mw field for CANUART IO isolation. If the mw field matches the magicword value then the value is latched into the CANUART IO voltage domain and CANUART IO isolation is activated. 0 - Unlock and do not load mw value for comparison 1 - Load and lock mw for magic word value comparison Reset Source: mcu_chip1_rst_n |
