Flash Control Register
The Flash Control register enables or disables memory access to Flash. I/O access to the
Flash control registers and I/O programming to Flash memory are still possible while
Flash memory space access is disabled.
The minimum access time of the internal Flash is 60 ns. The Flash control register must be
configured to provide the appropriate number of WAIT states based on the system clock
frequency of the eZ80F92 device. Default on RESET is for 4 WAIT states to be inserted
for Flash memory access.
