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 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
Table 93. ZDI Break Control Register (ZDI_BRK_CTL = 10h in the ZDI Write-
Only Register Address Space)
