OnCE Memory Breakpoint Logic
10.5.6
OnCE Breakpoint Control Register (OBCR)
The OBCR is a 16-bit register used to define the memory breakpoint events. OBCR can
be read or written through the JTAG port. All the bits of the OBCR are cleared by a
hardware RESET signal. The OBCR appears in
10.5.6.1
Memory Breakpoint Select (MBS0ÐMBS1)
Bits 0Ð1
The MBS0ÐMBS1 bits enable memory breakpoints 0 and 1, allowing them to occur when
a memory access is performed on P, X, or Y space. See
MBS0ÐMBS1 bits.
10.5.6.2
Breakpoint 0 Read/Write Select (RW00ÐRW01)
Bits 2Ð3
The RW00ÐRW01 bits define the memory breakpoint 0 to occur when a memory address
access is performed for read, write, or both. See
RW00ÐRW01 bits.
