Flash control register 1 high (FCR1H)

The Flash control register 1 high (FCR1H) and the Flash control register 1 low (FCR1L) are

used to select the sectors to erase, or they are used, during any write operation, to monitor

the status of each sector and each bank of the module selected by the SMOD bit of the

FCR0H register. FCR1H is shown below when SMOD = 0 and when SMOD = 1.
