| 31:1 | CANUART_WAKE_CTRL_MW_PROXY | R/W | 0h | CANUART IO magic word. The lower 23 bits determine if the device enters CANUART IO isolation when mw_load_en is set. If the lower 23 bits match the ACTIVATE value (0x5AAAAA), then CANUART IO Isolation is entered, any other value will prevent entry. The upper 8 bits of this register are software defined and do not determine whether or not CANUART IO isolation is entered. Field values (others are reserved): 31'h005AAAAA - ACTIVATE 31'h00000000 - DEACTIVATE Reset Source: mcu_chip1_rst_n |
| 0 | CANUART_WAKE_CTRL_MW_LOAD_EN_PROXY | R/W | 0h | Magic word load enable Setting this bit loads and locks the mw field for CANUART IO isolation. If the mw field matches ACTIVATE, CANUART IO Isolation is initiated. Field values (others are reserved): 1'b0 - UNLOCK 1'b1 - LOCK_AND_LOAD Reset Source: mcu_chip1_rst_n |
