Figure 4.4.6. Example of RDY circuit holding state of bus for 1 BCLK
(2) RDY function usage
To use the RDY function, set a software wait.
The RDY function operates when the BCLK signal falls with the RDY pin at “L”; the bus does not vary
for 1 BCLK, and the state at that moment is held.
The RDY function holds the state of bus for the period in which the RDY pin is at “L”, and releases it
when the BCLK signal falls with the RDY pin at “H”. Figure 4.4.6 shows an example of RDY circuit
that holds the state of bus for 1 BCLK.
