22 | (RO) the state of RSU system. | |
23 | The state field has two parts: major error code in | |
24 | upper 16 bits and minor error code in lower 16 bits. | |
25 | ||
26 | b[15:0] | |
27 | Currently used only when major error is 0xF006 | |
28 | (CPU watchdog timeout), in which case the minor | |
29 | error code is the value reported by CPU to | |
30 | firmware through the RSU notify command before | |
31 | the watchdog timeout occurs. | |
