Variable Memory Cycles
External bus cycles of the XC164 are executed in five subsequent 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.).
This table provides a summary of the phases and the respective choices for their
duration.

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).
