ZDI_WR_MEM

A write to the ZDI Write Memory register, listed in
to write the 8-bit data to the memory location specified by the current address in the pro-
gram counter. In Z80
MEMORY mode, this address is PC[23:0]. The program counter, PC, increments after
each data write. However, the ZDI register address does not increment automatically when
this register is accessed. As a result, the ZDI master is allowed to write any number of data
bytes by writing to this address one time, and then writing any number of data bytes.
The Product ID Low and High Byte registers, listed in
provide a means for an external device to determine the particular Product product being
addressed. For the eZ80190 device, these two bytes {ZDI_ID_H, ZDI_ID_L}, return the
value {

The 8-bit data that is transferred to the ZDI slave following a
write to this address is written to the address indicated by the
current program counter. The program counter is incremented
following each 8-bits of data. In Z80 MEMORY mode, ({MBASE,

These registers contain the Op Codes and operands for
immediate execution by the CPU following a write to
ZDI_IS0. The ZDI_IS0 register contains the first Op Code
of the instruction. The remaining ZDI_ISx registers contain
any additional Op Codes or operand dates required for
execution of the required instruction.
