Cross Trigger InterfaceTable 15-5 shows how the bit values correspond with the CTIINTACK Registerfunctions.Table 15-5 CTI Interrupt Acknowledge Register bit functionsBits Field Function[31:9] - SBZ.[8] nCTIIRQ acknowledge Acknowledges the nCTIIRQ output:0 = no acknowledgement1 = nCTIIRQ is acknowledged and is deasserted.[7:0] - SBZ.15.6.3 CTI Application Trigger Set Register, CTIAPPSETCTIAPPSET is a read/write register. A write to this register generates a channel event,corresponding to the bit written to.Figure 15-6 shows the bit arrangement of the CTIAPPSET Register.31 4 3 0ReservedAPPSETFigure 15-6 CTI Application Trigger Set Register formatTable 15-6 shows how the bit value corresponds with the CTIAPPSET Registerfunctions.Table 15-6 CTI Application Trigger Set Register bit functionsBits Field Function[31:4] - Reserved. RAZ, SBZ.[3:0] APPSET Setting a bit HIGH generates an event for the selected channel.For read:0 = application trigger inactive (reset)1 = application trigger active.For write:0 = no effect1 = generate channel event.There is one bit of the register for each channel.15-14 Copyright © 2006-2008 ARM Limited.
