Caution:
Flash Controller Bypass
Flash Controller Behavior in DEBUG Mode
value
Controller executes the Mass Erase operation, the eZ8 CPU idles but the system clock and
on-chip peripherals continue to operate. Using the On-Chip Debugger, poll the Flash
Status register to determine when the Mass Erase operation is complete. When the Mass
Erase is complete, the Flash Controller returns to its locked state.
The Flash Controller can be bypassed and the control signals for the Flash memory
brought out to the GPIO pins. Bypassing the Flash Controller allows faster Row Program-
ming algorithms by controlling the Flash programming signals directly.
Row programing is recommended for gang programming applications and large volume
customers who do not require in-circuit initial programming of the Flash memory. Page
Erase operations are also supported when the Flash Controller is bypassed.
For more information on bypassing the Flash Controller, refer to Third-Party Flash Pro-
gramming Support for Z8 Encore! (AN0117) available for download at www.zilog.com.
The following changes in behavior of the Flash Controller occur when the Flash
Controller is accessed using the On-Chip Debugger:

For security reasons, Flash controller allows only a single page to be opened for write/
erase. When writing multiple Flash pages, the Flash controller must go through the un-
lock sequence again to select another page.
The Flash Write Protect option bit is ignored
The Flash Sector Protect register is ignored for programming and erase operations
Programming operations are not limited to the page selected in the Page Select
register
Bits in the Flash Sector Protect register can be written to one or zero
The second write of the Page Select register to unlock the Flash Controller is not
necessary
The Page Select register can be written when the Flash Controller is unlocked
The Mass Erase command is enabled through the Flash Control register
