ZDI Write Memory Register
A Write to the ZDI Write Memory register causes the eZ80F92 device to write the 8-bit
data to the memory location specified by the current address in the program counter. In
Z80 MEMORY mode, this address is {MBASE, PC[15:0]}. In ADL 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 writ-
ing to this address one time followed by any number of data bytes. See ZDI Write Memory
Register.

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, PC[15:0]})
