Data Bus Connected with CPU
The data bus connected with CPU is available either once for 8 bits or twice for 4 bits. This
allows the MSM6222B-xx to be interfaced with either an 8-bit or 4-bit CPU.

(2) When the interface data length is 4 bits

one step.
The 8-bit data input/output is carried out in two steps by using only high-order 4 bits
of data buses DB
The first time data input/output is made for 4-high order bits (DB
interfaces data length is 8 bits) and the second time data input/output is made for low-
order 4 bits (DB
input/output can be completely made through high-order 4 bits, be sure to make
another input/output of low-order 4 bits. (Example: Busy flag Read).
Since the data input/output is carried out in two steps but as one execution, no normal
data transfer is executed from the next input/output if accessed only once.
