10.2
Important timing characteristics of the external bus interface have been made user
programmable to allow to adapt it to a wide range of different external bus and memory
configurations with different types of memories and/or peripherals.
The following parameters of an external bus cycle are programmable:
• LE Control defines the ALE signal length and the address hold time after its falling
• Memory Cycle Time (extendable with 1...15 waitstates) defines the allowable access
• Memory Tri-State Time (extendable with 1 waitstate) defines the time for a data driver
• Read/Write Delay Time defines when a command is activated after the falling edge of
• READY Control defines, if a bus cycle is terminated internally or externally
Note: Internal accesses are executed with maximum speed and therefore are not

programmable.
External acceses use the slowest possible bus cycle after reset. The bus cycle
timing may then be optimized by the initialization software.
