The ALE signal latches an address of the multiplexed bus. Latch an address on the falling edge of the
ALE signal. The PM15 to PM14 bits in the PM1 register determine the output pin for the ALE signal.
The ALE signal is output to an internal space and external space.
The RDY signal facilitates access to external devices which need longer access time. When an "L" signal
is applied to the RDY pin on the falling edge of last BCLK of the bus cycle, wait states are inserted into the
bus cycle. When an "H" signal is applied to the RDY pin on the falling edge of the BCLK, the bus cycle
starts running again.
Table 7.6 lists microcomputer states when the RDY signal inserts wait states into the bus cycle. Figure
7.7 shows an example of the RD signal extended by the RDY signal.
