Programmable Registers
HW_DIGCTL_DEBUG_TRAP_SET: 0x2B4
HW_DIGCTL_DEBUG_TRAP_CLR: 0x2B8
HW_DIGCTL_DEBUG_TRAP_TOG: 0x2BC
This register sets the lower address that defines the debug trap function. When this function
is enabled, any active AHB cycle on either Layer 0 or Layer 0 which accesses this range
will trigger an interrupt to the ARM core.
