9.6.3
Idle cycles can be inserted to prevent extension of the RD or WRL signal assert period beyond the
length of the CS0 signal assert period by setting the SW0 bit of BCR2. This allows for flexible
interfaces with external circuitry. The timing is shown in figure 9.6. T
respectively before and after the normal cycle. Only CS0 is asserted in these cycles; RD and WRL
signals are not. Further, data is extended up to the T
the like, which have slower write operations.
