Address Information for 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 occurs only
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 instruc-
tion. The
bit is set to 1. The
bit must be reset to 0 to release the break.
