MTB_AUTHSTAT[3:2] indicates if nonsecure, noninvasive debug is enabled ordisabled, while MTB_AUTHSTAT[1:0] indicates the enabled/disabled state ofnonsecure, invasive debug. For both 2-bit fields, 0b10 indicates the functionality isdisabled and 0b11 indicates it is enabled.Address: F000_0000h base + FB8h offset = F000_0FB8hBit 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16R 0WReset 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0Bit 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0R 0 1 BIT2 1 BIT0WReset 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0MTB_AUTHSTAT field descriptionsField Description31–4ReservedThis field is reserved.This read-only field is reserved and always has the value 0.3ReservedBIT3This read-only field is reserved and always has the value 1.2BIT2BIT2Connected to NIDEN or DBGEN signal.1ReservedBIT1This read-only field is reserved and always has the value 1.0BIT0Connected to DBGEN.43.3.1.11 Device Architecture Register (MTB_DEVICEARCH)This register indicates the device architecture.
