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
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
Table 102. ZDI Write Memory Register(ZDI_WR_MEM = 30h in the ZDI Register Write
