Preliminary
Variable Memory Cycles
External bus cycles of the XC2766X are executed in five consecutive cycle phases (AB,
C, D, E, F). The duration of each cycle phase is programmable (via the TCONCSx
registers) to adapt the external bus cycles to the respective external module (memory,
peripheral, etc.).
The duration of the access phase can optionally be controlled by the external module
using the READY handshake input.
This table provides a summary of the phases and the ranges for their length.

whole operating range (temperature, voltage) as well as process variations. Within
a given device, however, this bandwidth is smaller than the specified range. This
is also due to interdependencies between certain parameters. Some of these
interdependencies are described in additional notes (see standard timing).
