arm7_9_debug_entry() function

Handle an ARM7/9 target's entry into debug mode. The halt is cleared on the ARM. The JTAG queue is then executed and the reason for debug entry is examined. Once done, the target is verified to be halted and the processor is forced into ARM mode. The core registers are saved for the current core mode and the program counter (register 15) is updated as needed. The core registers and CPSR and SPSR are saved for restoration later.

Syntax

Implemented in arm7_9_common.c:1225

Arguments
