In order not to exceed the limit values listed above, a specific CKCTL setting requires a minimum
CPU clock frequency, as listed below.
The maximum number of allowed programming or erase attempts depends on the CPU clock
frequency and on the CKCTL setting chosen in turn. This number results from the actual pulse width
compared to the maximum pulse width (see above tables).
The table below lists some sample frequencies, the respective recommended CKCTL setting and
the resulting maximum number of program / erase pulses:
BE:
The Flash
Bank Erasing
bit field determines the Flash memory bank to be erased (see table
below). The physical addresses of the selected bank depend on the Flash memory mapping
chosen.
