(5) The RDY signal
________
RDY is a signal that facilitates access to an external device that requires long access time. As shown in
________
Figure 1.9.4, if an “L” is being input to the RDY at the BCLK falling edge, the bus turns to the wait state. If
________
an “H” is being input to the RDY pin at the BCLK falling edge, the bus cancels the wait state. Table 1.9.5
shows the state of the microcomputer with the bus in the wait state, and Figure 1.9.4 shows an example
____
________
in which the RD signal is prolonged by the RDY signal.
________
The RDY signal is valid when accessing the external area during the bus cycle in which bits 4 to 7 of the
________
chip select control register (address 000816) are set to “0”. The RDY signal is invalid when setting “1” to
________
all bits 4 to 7 of the chip select control register (address 000816), but the RDY pin should be treated as
properly as in non-using.
