13.16.4 Flash Write Timing
The Flash Controller contains a timing
generator which controls the timing
sequence of flash write and erase
operations. The timing generator uses the
information set in the Flash Write Timing
register, FWT.FWT[5:0], to set the
internal timing. FWT.FWT[5:0] must be
set to a value according to the currently
selected system clock frequency.
The value set in the FWT.FWT[5:0] shall
be set according to the system clock
frequency by the following equation.
21000 ∗ F
FWT =
16 *10⁹
Where F is the system clock frequency.
The initial value held in FWT.FWT[5:0]
after a reset is 0x11 which corresponds to
13 MHz CPU clock frequency (High speed
RC oscillator).
The FWT values for the possible system
clock frequencies are given in Table 55.
