If interface data is 8-bits long

Example of interfacing to an 8-bit MPU(Z80)

Example of interface to a 4-bit MPU

Interface to a 4-bit MPU can be made through the I/O port of the 4-bit MPU. If there are sufficient I/O ports,

data can be transferred at 8-bit cycles, however, if there are not, data transfer can be accomplished by two

cycles of 4-bit transfers (select interface as 4-bits long). Please take into account that 2 cycles of the BF check

will be necessary and the timing sequence will prove to be complicated.
