IMING
The signals used in the Motorola microprocessor interface mode are: Address Strobe (AS), Data Strobe (DS),
Read/Write Enable (R/W), Chip Select (CS), Address and Data bits. The interface is compatible with the timing
of a Motorola 68000 microprocessor family with up to 16.67 MHz clock frequency. The interface timing is
shown in
Figure 31
and
Figure 32
. The I/O specifications are shown in
Table 50
.
