Table 96. ZDI Address Match Registers
ZDI_ADDR0_L = 00h, ZDI_ADDR0_H = 01h, ZDI_ADDR0_U = 02h,
ZDI_ADDR1_L = 04h, ZDI_ADDR1_H = 05h, ZDI_ADDR1_U = 06h,
ZDI_ADDR2_L = 08h, ZDI_ADDR2_H = 09h, ZDI_ADDR2_U = 0Ah,
ZDI_ADDR3_L = 0Ch, ZDI_ADDR3_H = 0Dh, and
ZDI_ADDR3_U = 0Eh in the ZDI Register Write Only Address Space
ZDI BREAK Control Register
The ZDI BREAK Control register is used to enable BREAK points. ZDI asserts a BREAK
when the CPU instruction address, ADDR[23:0], matches the value in the ZDI Address
Match 3 registers, {ZDI_ADDR3_U, ZDI_ADDR3_H, ZDI_ADDR3_L}. BREAKs can
only occur on an instruction boundary. If the instruction address is not the beginning of an
instruction (that is, for multibyte instructions), then the BREAK occurs at the end of the
current instruction. The BRK_NEXT bit is set to 1. The BRK_NEXT bit must be reset to
0 to release the BREAK. See ZDI BREAK Control Register.

The four sets of ZDI address match registers are used for
setting the addresses for generating BREAK points. The
24-bit addresses are supplied by {ZDI_ADDRx_U,
ZDI_ADDRx_H, ZDI_ADDRx_L, where x is 0, 1, 2, or 3.
