Debug Events C3.3 Halting debug events A Halting debug event is one of the following: An External Debug Request debug event. This is a request from the system for the processor to enter Debug state. The method of generating an External Debug Request is IMPLEMENTATION DEFINED. Typically it is by asserting an External Debug Request input to the processor. A Halt Request debug event. This occurs when the debug logic receives a Halt request command. In v7 Debug, a debugger generates a Halt request command by writing 1 to the DBGDRCR Halt request bit, see Debug Run Control Register (DBGDRCR), v7 Debug only on page C10-29. An OS Unlock Catch debug event. This occurs when both of the following are true: — the OS Unlock Catch is enabled in the Event Catch Register — the OS Lock transitions from the locked to the unlocked condition. For details see Event Catch Register (DBGECR) on page C10-78 and OS Lock Access Register (DBGOSLAR) on page C10-75. If invasive debug is disabled when one of these events is detected, the request is ignored and no Halting debug event occurs. Invasive debug is disabled when the external debug interface signal DBGEN is LOW. If DBGEN is HIGH, meaning that invasive debug is enabled, and a Halting debug event occurs when it is not permitted, the Halting debug event is pended. This means that the processor enters Debug state when it transitions to a security state or processor mode where the Halting debug event is permitted. However, if DBGEN goes LOW before the processor enters the security state or processor mode where the Halting debug event is permitted, it is UNPREDICTABLE whether the event remains pended. If the debug logic is reset before the processor enters the permitted security state or processor mode, the processor must remove pending Halt Request and OS Unlock catch debug events. Whether a pending External Debug Request debug event is removed is IMPLEMENTATION DEFINED. Note The IMPLEMENTATION DEFINED details of External Debug Request might specify that it is pended externally by the peripheral that is driving it until the processor acknowledges the request by entering Debug state. In such a system the pending request is typically held over a debug logic reset. If a Halting debug event occurs when debug is enabled and the event is permitted, or the Halting debug event becomes permitted while it is pending, it is guaranteed that Debug state is entered by the end of the next Instruction Synchronization Barrier (ISB) operation, exception entry, or exception return. See Run-control and cross-triggering signals on page AppxA-5 for details of the recommended external debug interface. C3-38 Copyright © 1996-1998, 2000, 2004-2008 ARM Limited. All rights reserved. ARM DDI 0406B
In v6 Debug and v6.1 Debug: Debug Events if the processor implements the recommended ARM Debug Interface v4, the Halt request command is issued through the JTAG interface, by placing the HALT instruction in the IR and taking the Debug Test Access Port State Machine (Debug TAP State Machine) through the Run-Test/Idle state the OS Unlock Catch debug event is not supported. In v6 Debug it is IMPLEMENTATION DEFINED whether Halting debug events cause entry to Debug state when Halting debug-mode is not configured and enabled.
