ZDI Address Match Registers
The four sets of address match registers are used for setting the addresses for generating
break points. When the accompanying BRK_ADDRx bit is set in the ZDI Break Control
register to enable the particular address match, the current eZ80L92 address is compared
with the 3-byte address set, {ZDI_ADDRx_U, ZDI_ADDRx_H, ZDI_ADDR_x_L}. If
the CPU is operating in ADL mode, the address is supplied by ADDR[23:0]. If the CPU is
operating in Z80 mode, the address is supplied by {MBASE[7:0], ADDR[15:0]}. If a
match is found, ZDI issues a BREAK to the eZ80L92 placing the processor in ZDI mode
pending further instructions from the ZDI interface block. If the address is not the first op-
code fetch, the ZDI BREAK is executed at the end of the instruction in which it is exe-
cuted. There are four sets of address match registers. They can be used in conjunction with
each other to break on branching instructions. See
