ZDI Register Definitions
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 eZ80F91 address is compared
with the 3-byte address set, {ZDI_ADDRx_U, ZDI_ADDRx_H, and 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
match is found, ZDI issues a break to the eZ80F91 device placing the CPU 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 executed.
There are four sets of address match registers. They are used in conjunction with each
other to break on branching instructions. See
