10.5.6.5
Breakpoint 1 Condition Code Select (CC10–CC11) Bits8–9
The Breakpoint 1 Condition Code Select bits (CC10–CC11) define the condition of the
comparison between the current memory address (OMAL0) and the OnCE Memory
Limit Register 1 (OMLR1). See Table 10-10 for the definition of the CC10–CC11 bits.
10.5.6.6
Breakpoint 0 and 1 Event Select (BT0–BT1) Bits10–11
The Breakpoint 0 and 1 Event Select bits (BT0–BT1) define the sequence between
Breakpoint0 and 1. If the condition defined by BT0–BT1 is met, then the Breakpoint
Counter (OMBC) is decremented. See Table 10-11 for the definition of the BT0–BT1 bits.
10.5.6.7
OnCE Memory Breakpoint Counter (OMBC)
The OnCE Memory Breakpoint Counter (OMBC) is a 16-bit counter that is loaded with a
value equal to the number of times minus one that a memory access event should occur
before a memory breakpoint is declared. The memory access event is specified by the
OBCR and by the memory limit registers. On each occurrence of the memory access
event, the breakpoint counter is decremented. When the counter reaches 0 and a new
occurrence takes place, the chip enters the Debug mode. The OMBC can be read or
written through the JTAG port. Every time that the limit register is changed, or a
different breakpoint event is selected in the OBCR, the breakpoint counter must be
written afterwards. This ensures that the OnCE breakpoint logic is reset and that no
previous events can affect the new breakpoint event selected. The breakpoint counter is
cleared by hardware reset.
