CTIDEVID CTI Device ID register 0 CTIDEVID is in the Debug power domain CTI 0xFC8 CTIDEVID RO Describes the CTI component to the debugger. CTI CTIDEVID is a 32-bit register. 31 26 31:26 Reserved, RES0. INOUT 25 24 25:24 Input/output options. Indicates presence of the input gate. If the CTM is not implemented or CTIv2 is not implemented, this field is RAZ. All other values are reserved. 0b00 CTIGATE does not mask propagation of input events from external channels. 0b01 CTIGATE masks propagation of input events from external channels. RO 23 22 23:22 Reserved, RES0. NUMCHAN 21 16 21:16 Number of ECT channels implemented. For Armv8, valid values are: 0b000011 3 channels (0..2) implemented. 0b000100 4 channels (0..3) implemented. 0b000101 5 channels (0..4) implemented. 0b000110 6 channels (0..5) implemented. and so on up to 0b100000, 32 channels (0..31) implemented. All other values are reserved. This field has an IMPLEMENTATION DEFINED value. RO 15 14 15:14 Reserved, RES0. NUMTRIG 13 8 13:8 Upper bound for number of triggers. The indices of all implemented input and output triggers are less than this value. There is no guarantee that all of the input and output triggers, including the highest numbered, are connected to any components, or that the implementation of input and output triggers is symmetrical. This field has an IMPLEMENTATION DEFINED value. RO 7 5 7:5 Reserved, RES0. EXTMUXNUM 4 0 4:0 Number of multiplexors available on triggers. This value is used in conjunction with External Control register, ASICCTL. This field has an IMPLEMENTATION DEFINED value. RO 2026-03-26 20:27:25 2026-03_rel
