The Flash Control Register (FCR)

In standard operation mode the Flash memory can be accessed like the normal mask-

programmable on-chip ROM of the SAB 83C166. So all appropriate direct and indirect addressing

modes can be used for reading the Flash memory.

All programming or erase operations of the Flash memory are controlled via the 16-bit Flash control

register FCR. To prevent unintentional writing to the Flash memory the FCR is locked and inactive

during standard operation mode. Before a valid access to the FCR is enabled, the Flash memory

writing mode must be entered. This is done via a special key code instruction sequence.
