Motorola Interface Timing
The signals used in the Motorola microprocessor in-
terface 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 in-
terface timing is shown in Figure 21, Figure 22 and
Figure 23. The I/O specifications are shown in
Table 20.
